Initial velocity(u)- 0 m/s^2
Final velocity (v)- 70m/s^2
distance travelled- 280m
now putting formula- v^2-u^2= 2as
4900=2a×280
4900= 560a
a=4900/560
a=70/8
a= 8.75m/s^2
Final velocity (v)- 70m/s^2
distance travelled- 280m
now putting formula- v^2-u^2= 2as
4900=2a×280
4900= 560a
a=4900/560
a=70/8
a= 8.75m/s^2
