Question

A car moving with a velocity of 10m/s accelerated uniformly at 1 meter per second square untill it reaches a velocity of 15m/s. calculate the time taken, the distance travelled during the acceleration and velocity reached 100m from the place where acceleration
began.

Answer 1

Answer:

7.5

Explanation:

v=u+at

15=10+1t

t=5

v^2-u^2=2as

225-100=2.1.s

s=62.5

100-62.5=37.5

s'=ut-1/2at^2

37.5=15t

t=2.5

t=5+2.5=7.5
