Question

Figure shows the graph of time versus velocity of a particle moving. Find out particles initial velocity and acceleration from the graph. Unot is SI​

Answer 1

initial velocity=velocity at t=0

acceleration=slope off v-t graph

$a = y \frac{}{2} - y \frac{}{1} \div x \frac{}{2} - x \frac{}{1 } \\ = 9 - 4 \div 5 - 0 = 5 \div 5 \\ = 1m \div sec {}^{2}$
