Question

A body at rest covers a distance of 5 km in 10 minutes then the acceleration gained by the body is?

Answer 1

Answer:

The initial velocity travelled is 625m

The accleration is α=10m/s

2

The time is t=5s

Apply the equation of motion

v=u+at

The velocity is v=0+10.5=50m/s.

The distance travelled in the first 5s is

s=ut+
