hey dear
here is your answer
given data :
mass (m) = 150 kg
force (f) = 95 N
final velocity (v) = 0
tine taken (t) = 5 seconds
to find : initial velocity (u)
solution :
force = mass×acceleration
95 = 150×a
a = 95/150
a = 0.63 m/s^2
now, by using 1st equation of motion
v = u+at
0 = u-0.63×5
u = 3.15 m/s
hope it helps :)
