1. At what instant of time (between time zero and time tend) is the cart farthest to the WEST of the origin?
2. What is the cart's distance from the origin at the location in time described in part G? This will be the cart's maximum distance to the WEST of the origin.

Human pushing forces often create accelerations that fit this description; the pushing force is small when the hands of the human first make contact (assuming the fingertips touch first), large when the palms are flat against the object being pushed, and then small again as the fingertips are...
A cart of mass m rolls without friction on a level
surface, and is attached to a light spring of constant k,
the other end of which is attached to a wall. Take the initial
position of the cart, where the spring is neither extended nor
compressed, to be the origin x = 0 of a coordinate system
where positive x values are to the right and positive
vectors point to the right. The cart is pushed to the left...

For the following velocity graph, velocity is in m/s and time is in What is the acceleration of the object (i) between t = 0 and t = 1s; (ii) between t = 1s and t = 2s; (iii) between t = 2s and f = 5s; (iv) between t = 5s and t = 6s? If the object is initially at x = -5m, what is its position at t = Is, t = 2s, t = 5s, and...
3 Select the THREE responses that are correct. If an object's position versus time graph is a straight line with a positive slope, then that object is moving with a constant velocity. moving with zero acceleration. moving upward. moving with a constant speed. moving with a constant, non-zero acceleration.4 An object can reverse its direction of travel when it has a constant acceleration. True False 5 Let us take up to the positive direction. If you throw a small rock straight up and catch it when it returns to you, its velocity vs....

Place t hat Place two photogales in gate mode along the track and record the distance between the gates 3 Release the and to Release the cart from the top of the track and record the time it takes the cart to pass through each gate...
please answer as many questions as possible. I will “thumb up” the
answers. Thanks!

1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...
