Question

Define acceleration and give its SI unit a bus decreases its speed from 80 km / hr to 60 km / hr in 5 sec , find acceleration of the bus.​

Answer 1

Answer:

Rate of change in velocity is known as acceleration.

SI unit=m/s^2

answer of numerical= 4m/s^2

Explanation:

acceleration= v-u/t

v= 80

u=60

t=5

acceleration (g)=80-60/5

=4m/s^2

Hope this helps you:)
