Question

Calculate the force required to inpart to a car of velocity 30m/s2 in 10s starting from rest.the mass of the car is 1500kg

Answer 1

v=u+at
u=0
30=0+a*10
a=3 m/s*s

f=ma
1500*3
4500 N

Answer 2

here,
u=0m/s^-2
v=30m/s^-2
t= 10s
m=1500kg
F=?
From Newton's second law of motion,
F=ma
F=m(v-u/t)
F=1500(30-0/10)
F=1500*3
F=4500N
