Question

Calculate the force needed to make a car of mass 1500kg starting from rest to reach a velocity of 30m/s in 10s if it accelerates uniformly.​

Answer 1

Answer:

Here,

initial velocity of car(u)=0ms  

−1

 

final velocity of car (v)=30ms  

−1

 

time(t)=10s

we know,

v=u+at

30=0+a(10)

a=3ms  

−2

 

we know,

F=ma

=1500×3

or F=4500N
