Question

A car travels at a constant 60 km per hour in the positive direction down a straight-line highway. What is the displacement, in standard units, of the car 45 seconds later?

Answer 1

Answer:

The displacement of the car is 750.15 m

Explanation:

Given;

constant velocity of the car, v = 60 km/h

Convert the velocity to m/s by dividing by 3.6 = (60 /3.6) =  16.67 m/s

time of motion, t = 45 s

The displacement of the car is calculated as;

displacement = velocity x time

displacement = 16.67 m/s x 45s

displacement = 750.15 m

Therefore, the displacement of the car is 750.15 m
