A BUS OF MASS 5000KG START FROM REST AND ROLLS DOWN A HILL . IF IT TRAVELS A DISTANCE OF 200M IN 10 SECONDS.FIND THE ACCLERATION OF BUS AND FORCE ACTING ON THE BUS?

answered-by-expert Expert Answer
displacement, s = 200 m
time, t = 10 s
thus using the second equation of motion, we an say that
s = 1/2at2 (as initial velocity is 0)
thus a = 4 m/ss
thus force on the bus wil be = ma = 2000N
