Figure shows the graph of the x-coordinaste of a particle going along the X-axis as a function of time.Find a. te average velocity during 0 to 10s, b. instantaneous velocity at 2,5,8 and 12s.

Answer

A, B

Explanation

a. Displacement in 0 to 10 sec is 100 m
time = 10 sec
`V_(av)=S/t= 100/10= 10 m/s

b. Uniform velocity at which it is movkng at 2.5 sec
`=50/2.5=20 m/s
At 2.5 sec
V_(inst)= 20 m/s
At 5 sec
velocity is -ve as it moves towards position. V_(inst)=-20 m/s`
