a) final velocity=72km/h
=20m/s
initial velocity=o m/s
time=10 seconds
acceleration=(20-0)/10
=2m/s^2
b)average velocity =22.4/10
=2.24 m/s
c) distance=ut+1/2at^2
=100 m
=20m/s
initial velocity=o m/s
time=10 seconds
acceleration=(20-0)/10
=2m/s^2
b)average velocity =22.4/10
=2.24 m/s
c) distance=ut+1/2at^2
=100 m
