When a ball is thrown upward, what are its velocity and acceleration at its highest point? Chapter 4 (a) If an object bat rest, there must be no forces acting on it. Is this statement correct? Explain. (b) If the net force on an object is zero, can you conclude that the object is at rest? Explain

Explanation / Answer

a) when a car moves in a circular track with constant speed then it has centri petal acceleration.

b) when a ball moves to a max height at that point it has zero velocity but it has acceleration due to gravity acts downwards

c) no , when a object is at rest there are force acting on an object but net force is zero

d) if net force is zero then the object is at rest or moving with a constant velocity.
