Physics - Kinematics Question with Solution | TestHub

Average velocity of particle from $\mathrm{t}=0$ to $\mathrm{t}=15\sec$ is zero

Average velocity of particle from time $\mathrm{t}=0$ to $\mathrm{t}=7.5\sec$ is same as from $\mathrm{t}=0$ to $\mathrm{t}=15\sec$.

Average speed of particle from time $\mathrm{t}=5$ to $\mathrm{t}=10\sec$ is $4\mathrm{m}/\mathrm{s}$

Maximum speed of the particle is $4\mathrm{m}/\mathrm{s}$
