Question

i)what is the velocity of a body at point c. ii)what is the acceleration acting on the body between A and B. iii)what is the acceleration acting on the body between B and C.​

Answer 1

Answer:

i) BC represents uniform velocity. From graph, we see that the velocity of the body at point C = 40km/h.

(ii) Acceleration between A and B = slope of line AB.

(iii) BC represents uniform velocity, so acceleration acting on the body between B and C is zero.

Answer 2

Answer :-

Velocity = displacement / time

• s/t

Acceleration = (change in velocity) / time

• ( v - u ) / t
