An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 3.8×104 kg, and the force causes its speed to change from 6900 to 5400 m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.4×106 m determine the magnitude of the force. (a) Work = (b) F =

A scientist builds an apparatus to measure the charge to mass ratio of ions. An ion is first accelerated to a speed of 4.50×107 m/s. It then passes through a region of magnetic field, with a magnitude of 2.44×10−2 T, perpendicular to the ion's velocity. Because the ion is moving so fast, it is only in the presence of the magnetic field for 2.00×10−7 s. Upon exiting the magnetic field, the scientist measures that the ion was deflected a distance of 3.00 cm in a direction perpendicular to its initial velocity. (a) What is the ratio of the absolute value of the ion's charge to its mass (in C/kg )? Assume the velocity change is small, and that the component of the velocity along the ion's original direction does not change noticeably. |q| m = Cg (b) Suppose the scientist determines the ion is singly charged; that is, the magnitude of its charge is that of a proton. What is the mass of the ion (in kg)? kg

Problem Statement: Dianne the Duck is moving along a straight line in a river. The net force on Dianne is shown on the graph below. (a) What is the total work done on Dianne as she moves from x = 0 m to x = 10 m? (b) If Dianne's mass is 1.25 kg, and she initially started her 10 m trip with a speed of 2.828 m/s (i. e. when she passed x = 0), what is her speed when she reaches x = 10 m?

Two blocks, labeled A and B, are connected by a massless string that runs over a massless and frictionless pulley. Block A is sliding up along an inclined plane with ordinary surface friction. The string from block A runs over the pulley and then to block B which hangs straight down. At the start of the experiment, block A is sliding up the plane and block B is moving downward, both at a speed of v0 = 1.5 m/s. Block A has a mass of 3.3 kg. Block B has a mass of 1.4 kg. The plane is inclined at an angle of 27 degrees above horizontal. The coefficient of kinetic friction between block A and the plane is 0.36 (no units). Assume that the only significant forces on the blocks are normal forces, tensions forces, friction from the inclined plane, and gravity (with g = 9.81 m/s2 ). From the start of the experiment, when block A is sliding up the plane at a speed of 1.5 m/s, how far (in units of meters) does block A slide before coming to a stop? Just one more "show your work" after this one. You will need to submit your solution for this question.
