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.
