Will a cart rolling up and down a ramp have a faster or slower acceleration than a ball being thrown straight up into the air? (assume up the ramp is positive and the origin is the starting point of the cart)

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

Which is not an example of how an object gains elastic potential energy by stretching? a. jumping on a pogo stick b. pulling on a rubber band c. jumping on a trampoline

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
