Question

A cart is pushed by Shyam with a force of 320 N.He could move it fast quite easily.
Now Arun starts pushing the cart with a force equal to 150 N in the opposite direction.Find the resultant force acting on the cart.

Answer 1

Answer:

250N

Explanation

because

150 + 100 = 250150+100=250

and they are pushing the cart in the same direction.

Answer 2

Answer:

Initially , the force exerted on the cart by Shyam was 320N but now that Arun is pushing it in the opposite direction with the force of 150N thus the resultant force is now 170 N . Lower the force applied , lower the acceleration and hence lower the velocity.

Explanation:

Initial pushing force= 320 N

Final pushing force= 320-150    =   170 N ( Resultant force )
