Question

A force of 50 N is required to push a car on a level road with constant speed of 10 m/s.the mass of the car is 500 kg .what force should be applied to make the car accelerate at 1 m/s2

Answer 1

Here we get frictional force as 50N

So By 1st law we get,

F=?

V=10m/s

M=500kg

Therefore, F-f=Ma

F=Ma+f

F=500*1+50

F=550 N

Here's your answer

Good luck

Answer 2

Answer: 550 N

Explanation:

Frictional force, f = 50N

Mass, m = 500 kg

Acceleration, a = 1 m/s²

Let required force be F

A T Q , by 2nd law of motion

F - f = ma

F = 500*1 + 50

Hence F = 550 N
