Question

plzz help me with this question

Answer 1

a) v=15m/s 

t=3s

a=v/t

=15/3

=5m/s²

b)Yes, since acceleration depends on both velocity and time, acceleration is present even when the velocity is constant

c)The car is slowing down(velocity is decreasing)

d)Distance=1/2*3*15(from graph)

=45/2

=22.5m

e)1/2*(3+10)*15

=1/2*13*15

=97.5m
