I would really appreciate some help with this problem... A cart is driven by a large propeller or fan, which can accelerate or decelerate the cart. The cart starts out at the position x = 0 m, with an initial velocity of +4.5 m/s and a constant acceleration due to the fan. The direction to the right is positive. The cart reaches a maximum position of x = +13.5 m, where it begins to travel in the negative direction. Find the acceleration of the cart.

Question

anonymous · Answer

They give you Velocity (4.5 m/s) and the displacement (13.5) so you can divide that to find the time.

Since $$Acc = \frac{ V }{ T }$$
