Question

A body travels a distance 10 m in 2 second and 40 m in next 2 second. Find distance travelled by the body in next 4 seconds

Answer 1

time=2s
distance=10m
initial velocity =10/2=5m/s

distance=40m
time =2s
fina velocity=40/2=20m/s
acceleration=(20-5)/2
=12.5m/s^2

there fore,distance travelled in next 4s=1/2×12.5×4^2
=100m
