A 1715 kg car accelerates from rest to 21 m/s. What energy E is required to accomplish this? Assume that no dissipative forces act on the car. E = J In terms of to the amount of energy E required to accelerate a car from rest to 21 m/s, how much additional energy ΔE is required to accelerate the car from 21 m/s to twice that speed, 42 m/s ? ΔE = 0 ΔE = 2E ΔE = 3E ΔE = 4E

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.

Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. It is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day. (i) A bird with these tendencies is released from an island that is 3 km from the nearest point B on a straight shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Points B and D are 10 km apart. Assume that the bird instinctively chooses a path that will minimize its energy expenditure. (Round your answers to two decimal places.) (a) In general, if it takes 1.2 times as much energy to fly over water as land, to what point C should the bird fly in order to minimize the total energy expended in returning to its nesting area? km from B (b) Let W and L denote the energy (in joules) per kilometer flown over water and land, respectively. Assuming the bird's energy expenditure is minimized, determine a function for the ratio WL in terms of x, the distance from B to C. W/L = (c) What should the value of W/L be in order for the bird to fly directly to its nesting area D? (d) If the ornithologists observe that birds of a certain species reach the shore at a point 2 km from B, how many times more energy does it take a bird to fly over water than land?
