53. The graph given alongside shows the positions of a body at different times
Calculate the speed of the body as it moves from:
(1) A to B
(in B to C, and
(in C to D.
1. What can you say about the motion of a body if:
(a) is displacement-time graph is a straight line ?
(b) its velocity-time graph is a straight line ?
A body with an initial velocity x moves with a uniform acceleration v. Plot
its velocity-time graph.
Given alongside is the velocity-time graph for a moving body:
Find: (1) Velocity of the body at point C.
(1) Acceleration acting on the body between A and B.
(i) Acceleration acting on the body between B and C
body is moving uniformly in a straight line with a velocity
of 5 m/s. Find graphically the distance covered by it in 5
exconds.
