Question

A object has initial velocity 25 m/sec and final velocity 21 m/sec. the object cover the distance in 30 second find acceleration of the object and also find the type of acceleration​

Answer 1

Answer:

It is given that U=25m/s , V=31 m/s and t=30 s

so , using 1st equation of motion

V=U + AT

21 =25 + A30

so

A=-2/15

so it is variable acceleration.

hope it's help you
