Question

Observe the figure showing the path of a body which started from

A and moved to C through B.

a. Calculate the speed of the body. 

b. What is the velocity of the body? 

c. What is the velocity of the body if it has taken 5 s to reach A hack from C?

d. Compare the velocity of the body when it reached C from A and also when it reached 

A from C.

Answer 1

a. Distance = 60 + 40 = 100 m

Time = 6 + 4 = 10 sec

∴ Speed = \(\frac{100}{10}\) = 10m/s

b. Velocity = \(\frac{displacement}{time}\) = \(\frac{70}{10}\) = 7m/s

c. displacement = 0, Velocity = 0

d. Velocity of the body when it reached C from A = 7 m/s

Velocity of the boby when it reached A from C velocity = 0 m/s
