A 1500 kg car on flat
ground is
moving 5.25 m/s. Its
engine
creates a 1250 N forward force as
the car moves 42.8 m. What is its
final velocity?
(Unit = m/s)

We determine the final velocity, vf, of the car. We do this by applying the kinematic equation,v2f=v2i+2adwhere vi is the initial velocity, a is the acceleration, and d is the distance covered across the movement. We can express the acceleration using the equation,a=Fmwhere F is the applied force and m is the mass of the car. We use the following values for the variables:vi=5.25 ms−1F=1250 Nm=1500 kgd=42.8 mWe proceed with the solution.v2f=v2i+2adv2f=v2i+2FdmTake the positive root.vf=√v2i+2Fdm=√(5.25 ms−1)2+2(1250 N)(42.8 m)1500 kg≈9.9 ms−1Help improve Study.com.
