Answer:1.549 kg-m/s
Explanation:
Given
mass of basketball =609 g
ball is moving downward right at an angle of 
with vertical
After hitting the floor it moves with a speed of 3 m/s
change in Momentum in x direction
where u=3m/s
v=3m/s
m=mass of ball
Change in momentum in Y-direction
Answer:
23: Acceleration 24:1m/s^2
Explanation:
Answer:
Yes – its direction is changing.
Explanation:
It is given that, a car rounds a curve while maintaining a constant speed. We know that on a circular curve, the object moves with constant speed. The velocity of object keeps on changing due to change in its direction. Here, the forces acting on the car are force of gravity and the centripetal force.
We can say that yes there is a net force on the car as it rounds the curve due to the change in its direction of motion. Hence, the correct option is (3).
