Answer:
15/4 m/sec^2
Explanation:
acceleration = rate of change of v with time.=
here v1=5m/sec
v2=20 m/sec
and t= 4 sec
so v2-v1= 20-5=15
so a=15/4 m/sec^2

Answer:
Acceleration=change of velocity/time
=final velocity-initial velocity/t
final velocity=20 m/s
initial velocity=5 m/s
time=4 sec
so, acceleration=20-5/4
=15/4=3.75
acceleration=3.75 m/s²
