Question

A ball thrown vertically upward reached a height of 80 m. Calculate :

a) the time to reach the highest point

b) the spend of the ball upon arrival on the ground.

24 A stone is thrown vertically upward which takes time ‘t’ to reach to maximum height ‘h’.

After next ‘t’ seconds it reached the ground from the maximum height. Draw

(i) distance-time graph and (ii) displacement time graph for the motion of the stone.

25 Draw V-t graphs in the following cases : (i) uniform retardation (ii) non uniform acceleration

26 From the following (V-t) graph find :

a) Distance and displacement in 10 second.

a) Distance and displacement in 15 second

27 a) A particle moves along a circle of radius R as shown in figure. It starts from A and moves in

anticlock-wise direction. Calculate the distance traveled and displacement :

(i) From A to B (ii) From A to C (iii) From A to D

b) Name a physical quantity that (i) varies (ii) remains same in a circular motion.​
