Question

A car travelling at a velocity of 15 ms due north speeds up uniformly to a velocity of 30 ms in 3 seconds. Calculate its acceleration

Answer 1

answer

5m/s^2

step by step explanation

*Given=>

a car travelling at a velocity of 15m/s due to north speed up uniformaly to a velocity of 30m/s in 3 sec.

*To Calculate=>

Acceleration

*Solution==>

final velocity (v)-30m/s

initial velocity(u)-15m/s

time taken(t)-3sec

we know that

a=v-u

t

a=acceleration

substituting values we get

===>. a=30-15

3

===>. a=15

3

===>. a=5m/s^2

acceleration =5m/s^2

Here is your answer
