4. Draw both a position-versus-time graph and a velocity-versus-time graph for an object at rest at x=1m. 5. The figure shows the position-versus-time graphs for two objects, A and B, that are moving along the same axis. At the instant t1 s, is the speed of A greater than, less than, or equa to the speed of B? Explain. b. Do objects A and B ever have the same speed? If so, at what time or times? Explain. 6. Below...

Two carts are riding on an air track as shown in the figure. At time t = 0 s, cart B is at the origin and traveling in the negative x direction with velocity v_B1. At that time, cart A is at the position shown and is at rest. Car B has twice the mass of cart A. The carts "bump" into each other but do not stick. Which physical parameter can be described by each of the following graphs?...

A cart starts at rest and rolls down a ramp as shown below. Gravity causes the cart to have a constant acceleration as it travels along the ramp. When it reaches the bottom of the ramp, friction with the flat surface causes it to gradually slow to a stop Draw graphs of the acceleration, velocity, and position of the cart throughout its motion as a function of time. The graphs should be laid out as they were on the computer...
An object moves along the x axis during four separate trials. Graphs of position versus time for each trial (with the same scales on each axis) are shown in the figure. (Figure 1)
Velocity from Graphs of Position versus Time An object moves along the x axis during four separate trials. Graphs of position versus time for each trial (with the same scales on each axis) are shown in the figure. (Figure 1) Part ADuring which trial or trials is the object's velocity not constant? Part B During which trial or trials is the magnitude of the average velocity the largest?
Allison throws a tennis ball at time t = 0 from a height h above the...
Allison throws a tennis ball at time t = 0 from a height h above the ground equal to her own height. We assume that the positive horizontal direction is the positive x-direction, and the positive vertical direction is the positive y-direction. The ball has a positive initial horizontal velocity vx, and no initial vertical velocity. At times t1 and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that...

A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...

and C?
Velocity at point B _______ m/s
Velocity at point C________ m/s
