Answer:
to the right.
Explanation:
Since the sign is not moving, the net force on this sign should be . For that, the horizontal component (
-component) of external forces on this sign should be
.
Sources of external forces on this sign include tension from the wires, as well as gravitational pull (weight) from the earth. The gravitational pull from the earth is entirely vertical (-component,) with a magnitude of
in the horizontal direction. Thus, the only external forces on this sign in the
-component would be from the two wires.
The question states that the -component of the force from the first wire is
to the left. Thus, for the net force in the
-direction to be
, the force from the other wire in the
-component needs to be
to the right (same magnitude but opposite direction.)
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.
