Answer 2

a)7m/s

b)2m/s.sq

Explanation:

a) Velcoity at 2.5 seconds is 7m/s

b) Acceleration = slope of velocity time graph

=(14−2)/(6−0)

=2m/s.sq.

c) Distance covered in last 4 seconds is the area under the curve for last 4 second

i.e.

Total distance covered in last 4 seconds

= area under ABCD

= area of ABED + area of BCE

=((6−0)×(6−2))+ (14−6)×(6−2)/2

=24+16

=40m
