1.What is the direction of velocity of an object moving in a circular path?
2.If a ball is thrown straight upwards at speed of 11m/s from balcony, 4m above ground, how much time would it take to strike the ground at the base of balcony?
3.A bullet of mass 10g moving with a velocity 400m/s gets embeded in a freely suspended woodenblock of 900g.what is the velocity acquired by the block?
                          can you answer my questions please!

Expert Answer:

When a particle moves on a circular path with a constant speed, then its motion is said to be a uniform circular motion in a plane. When a body moves along a circular path, then its direction of motion keeps changing continuosly.  For example if a car is moving with a constant speed along a circulat path, then the velocity of the car will not be a constant because velocity is the speed in a specified direction and here the direction of speed changes continuosly.
Thus we can say that for a body moving with a constant speed along a circular path:
1. The direction of velocity changes continuosly.
2. The direction of velocity at any point is along the tangent to the circle at that point in its motion.
Please ask other questions as a seperate query.
