Question

A shopping cart is given an initial velocity of 2 m/s and undergoes a constant acceleration of 4 m/s2. What is the magnitude of the cart’s displacement after the first 6 s of its motion?

Answer 1

Answer:

84 meters

Explanation:

Using these two kinematic equations : Vf= Vi +at and

D= [(Vi+Vf)/2]*t

Plugging in what we know into the first equation to solve for the Final velocity, you'll get Vf= 2 m/s + 4(m/s^2)*6s = 26m/s

plug time vi and vf into the second equation to solve for displacement.
