Given x=a+bt^2........eq 1
and a=5m b=2.5 m/s^2
putting value
x= 8.5 + 2.5t^2
for t=0
x = 8.5m/s
for t=2
x= 8.5+2.5×4
=18.5m/s
and for t=4
x=8.5+2.5×16
=48.5
average velocity
v = 48.5-18.5/2
= 30/2
= 15m/s
and a=5m b=2.5 m/s^2
putting value
x= 8.5 + 2.5t^2
for t=0
x = 8.5m/s
for t=2
x= 8.5+2.5×4
=18.5m/s
and for t=4
x=8.5+2.5×16
=48.5
average velocity
v = 48.5-18.5/2
= 30/2
= 15m/s
