Question

A body increases its speed from 20 m/s to 50 m/s in 10 seconds,it's acceleration is :​

Answer 1

Answer:

3m/s^2

Explanation:

acceleration= (final velocity) -(initial velocity)/time

which is: a = (v-u)/t

u (initial velocity) = 20m/s

v (final velocity)= 50m/s

t (time) = 10 seconds

Therefore,

acceleration = (50-20)/10

=30/10

= 3m/s^2

Hope this answers your question.
