Question

A car has a uniformly accelerated motion of 5 m/s^2. Find the speed acquired and distance traveled in 4 second from rest.

Answer 1

Explanation:

(a) Speedometer of a car is used to measure the instantaneous speed of the car.

(b) Odometer of a car is used to record and measure the overall distance travelled by the car.

Answer 2

Answer:

speed acquired is 20m/s and distance covered is 40m.

Explanation:

final speed or velocity, V= u + at

here, u=0m/, a=5m/s^2, t=4s

therefore v= 20m/s.

distance, s= ut + (1/2)at^2

by substituting the value we get

s= 40m.
