What can you say about the motion of a body if its displacement$-$time graph is a straight line parallel to the time axis ?
When is the acceleration $(i)$ positive $(ii)$ negative ?
A girl of mass $50\, kg$ jumps out of a moving boat of mass $300\, kg$ on to the bank with a horizontal velocity of $3\, m s ^{-1}$. With, what velocity, does the boat begin to move backwards ?
From the given $v -t$ graph (Fig.), it can be inferred that the object is
If the acceleration of a particle is constant in magnitude but not in direction, what type of path is followed by the particle ?
