Alab cart is given a push upward along a low-friction track. the initial speed of the cart is 4.0 m/s. if the acceleration is -3.0 m/s^2, calculate the time until the instantaneous velocity is zero and calculate the maximum displacement from the starting point.

i think the answer is a, hope this is right, that would be my best guess.

prolly a beacuse the momentuem the car has increases while going down hill

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
