Question

. A car moves with a velocity of 20 m/s. after 10 second its velocity changes to 40 m/s. Find acceleration of a car in m/ s^2 and cm/s^2

Answer 1

Explanation:

a= 40-20/10= 20/10=2 m/s^2

a= 200cm/s^2

Answer 2

Answer:

v = 20 m / s

time of change of velocity = 10 sec

change in velocity = 40 m/ s

acceleration = initial velocity - final velocity / time

in this case it is 40 -20/10 it is 20/10 acceleration is 2 m / s hope it helps u don't report me for spa. m and also mark me brainlies. t if u want don't pls report me. hope it helps you
