Question

A car accelerates from rest at 7.55 m/s2 for 4.25 s.

Determine the final velocity of the car.
And calculate the cars displacement.

Answer 1

Step-by-step explanation:

This problem is on the motion of a car.

given data.

acceleration a=7.55m/s

time t= 4.25 sec

1. Determine the final velocity of the car.

we know that

acceleration= velocity/time

substituting our given data we have

7.55= v/4.25

v=7.55*4.25

v=32.08m/s

2. calculate the cars displacement.

we also know that

velocity= distance/time

distance= velocity*time

distance= 32.04*4.25

distance= 136.37m
