The velocity-time graph of particle moving in straight line is given below. Three equal intervals t₁ = t₂ = t₃are shown. In which interval acceleration is constant, zero and variable? What is the acceleration at A and C?

Solution

Acceleration is constant in interval t₂, it is zero in the interval t₃and variable in the interval t₁.
At point A, the velocity is maximum. So, acceleration is zero.
The slope of v-t graph is zero at point C. Hence, acceleration is zero here.
