Question 1: Projectile motion in a constant gravity field A body of mass m = 1 kg, located 100 m above Earth's ground level, is kicked off horizontally with speed 2 m/s (see Fig. 1 a). Assume that the gravity acceleration is constant (g = 9.81 m/s2). How long after the initial kick-off will the body reach the ground? t1 = What would be the horizontal distance covered by the body at this time? R = What its speed would be then? vR = What is the total work produced/wasted from the gravity during the falling time? WR =

A mass m = 1.05 kg slides without friction from rest on a surface making a quarter circle with radius R = 1.55 m as shown in Figure 1. Then it lands on the top surface of a cart with mass M = 11.3 kg, that slides without friction on a horizontal surface. (In practise this cart could be a slider on an air track). Between the top of the cart and the mass m, the coefficient of static friction is μs = 1.07 and the coefficient of kinetic friction is μk = 0.959. The mass m slides a distance along the top of the cart but does not fall off. Figure 1: Diagrammatic representation of a block of mass m at the top of a quarter-circle surface of radius R that slopes down and to the right with decreasing absolute gradient towards a cart of mass M. The cart itself is resting on a horizontal surface. Part 1) What is the speed of the mass m immediately before it lands on the cart, M? v = ms−1 Part 2) What is the speed of the cart, M, when there is no longer any relative movement between m and M? V = m/s Part 3) How much mechanical energy is lost during the collision? (while m comes to rest relative to M). ΔE = −J Enter a positive number in the box if the final mechanical energy is less than the initial mechanical energy.

You are working during the summer at a company that builds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. (i) The rod is of length d = 1.00 m and mass m = 0.600 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 T. The electromagnetic force on the rod is parallel to the rails, causing the rod to roll to the right in the figure. When a full-scale device is produced, this rod will represent the axle of wheels on which the car and its passengers ride. The electromagnetic force on the axle will provide the motion of the car at the beginning of the roller-coaster ride. Your supervisor wants to test the substructure in the figure in a flat outdoor area on the grounds of the company. By projecting the rod from the rails in a horizontal direction from a height h = 2.20 m, the projection speed can be determined from how far from the ends of the rails the rod hits the ground. Your supervisor asks you to determine the length of the outdoor area needed to test the device. (Determine the total horizontal distance, in m, from the initial position of the rod on the tracks to the final position of the rod where it lands on the ground.) m

Robin would like to shoot an orange in a tree with his bow and arrow. The orange is hanging yf = 5.00 m above the ground. On his first try, Robin releases the arrow at v0 = 36.0 m/s at an angle of θ = 30.0∘ above the horizontal. The arrow has an initial height of y0 = 1.50 m, and its tip is x = 55.0 m away from the target orange. Treating the arrow as a point projectile and neglecting air resistance, what is the height of the arrow once it has reached the horizontal position x of the orange? Use g = 9.81 m/s2 for the acceleration due to gravity. height of the arrow: m For his second try, Robin decides to change his position but release the arrow using the same speed and angle as his first try. Assume that the orange remains in the same position. How far from the orange should Robin stand in order to hit the orange? There may be more than one correct distance. 6.4 m 108 m 11.6 m 60.2 m 103 m
