Answer:
False
Explanation:
For the vector to remain the same, the magnitude and the direction of the object must be constant. But when an object is travelling in a circular motion, it keeps on accelerating due to the change in direction, even if its motion is uniform. Quite clearly its velicity won't be constant although, its speed might be.
Answer: 2 s
Explanation: Change in momentum is equal to impulse which is J= Fxt
Derive the equation to find t.
t= J/F = 60/30= 2
Playing catch involves the ball moving in one direction in the air when you exert force. When the ball is in air, there is a gravitational force and a little it of backward air resistance until the other person catches it.
I think 100,375 J.
