The net horizontal force acting on the cart is 169.85 N.
The change in the carts momentum is 5,000 Ns.
The net horizontal force on Zanele is same as the net horizontal force on the cart.
If angle between the 500N force and the horizontal is decreased, the final velocity of the cart increases.
The given parameters:
- Mass of zanele, m1 = 40 kg
- Mass of the cart, m2 = 20 kg
- Applied force, F = 500 N, at angle 20 degrees
- Frictional force on the cart, Ff = 300 N
- Time, t = 10 s
- The net horizontal force acting on the cart is calculated as follows;
- The change in the carts momentum at the given time of applied force is calculated as follows;
The net horizontal force on Zanele is same as the net horizontal force on the cart.
<h3>The final velocity of the cart;</h3>- When the angle decreases the cart's final velocity would be affected as follows;
Thus, if angle between the 500N force and the horizontal is decreased, the final velocity of the cart increases.
