Question

Ques1. A body thrown vertically upward and returns back to the thrower after 6 seconds. Find- 1.velocity with which the body is thrown. 2.distance and displacement of the body after- (a) 1 sec (b) 2 sec (c) 3 sec (d) 4 sec (e) 5 sec (f) 6 sec 3. Using given data plot- (a) distance time graph (b) displacement time graph (c) speed time graph (d) velocity time graph (e) acceleration time graph 4. Can a body have zero velocity while moving with uniform acceleration. Explain with graph.

Answer 1

apply the equations of motion and conservation of energy. You will get the answers. Just remember one thing while calc. speed you must take distance and for velocity you should be taking displacement or change in position.
