An 18.0 N force pulls a cart against a 15.0 N frictional force. The speed of the cart increases 1.0 m/s every 5.0 s. What is the cart's mass?

Someone please help me on this I only have a few minutes

m = 15 kg

Explanation:

Applied force to the cart, F' = 18 N

Force of friction, f = 15 N

Net force acting on the cart,

F = F' - f

F = 18 - 15

F = 3 N

The change in velocity of the cart is 1 m/s every 5 s.

We need to find the mass of the cart.

The formula of net force is given by :

F = ma, where a is the acceleration of the cart

So, the cart's mass is 15 kg.

snell's law

refractve index = sin incidence / sin refraction
