Question

what is the normal force supporting a 1200kg car when a crane above it is pulling up on the car with a force of 500N

Answer 1

Given:

the mass of the car(m) = 1200 kg

crane is pulling a car with force = 500N

To Find:

normal force acting on car =?

Solution:

By drawing the free body diagram of the car, we get information like,

the normal force (N) = mg

here, acceleration due to gravity (g) = 10m/s²

thus, the normal force ( N) = 1200 × 10 = 12000 N = 12kN
