Question

A scooter moving at a velocity of 5m/s pocks up a velocity of 35m/s in 5s. Calculate the average acceleration.​

Answer 1

Answer:6m/s^2

Explanation:

Acceleration

=(final velocity - initial velocity)÷time taken

=(35m/s - 5 m/s)÷5 s

=30 m/s ÷5 s

=6 m/s^2

Answer 2

Average acceleration of the body will be $a=4m/sec^2$

Explanation:

We have given initial velocity of scooter u = 5 m/sec

And its pick up a velocity of 25 m/sec in 5 sec

So final velocity v = 25 m/sec

Time t = 5 sec

From first equation of motion we know that v = u+at

So $25=5+a\times 5$

$5a=20$

$a=4m/sec^2$

So average acceleration of the body will be $a=4m/sec^2$
