How can we draw a two objects $FBD$ according to Newton’s third law ?
A body, whose momentum is constant, must have constant
A rigid ball of mass $m$ strikes a rigid wall at $60^o $ and gets reflected without loss of speed as shown in the figure. The value of impulse imparted by the wall on the ball will be
A body of $2\, kg$ has an initial speed $5ms^{-1}$. A force acts on it for some time in the direction of motion. The force time graph is shown in figure. The final speed of the body. .......... $m{s^{ - 1}}$
A block of mass $2\, kg$ is suspended $5\,m$ from a string, is released from a height of $5\,m$ as shown in figure then what will be the impulse when string. Just becomes tight ............ $N-s$
A body of mass $5 \,kg$ is moving with a momentum of $10\, kg-m/s$. A force of $0.2 \,N$ acts on it in the direction of motion of the body for $10\, seconds$. The increase in its kinetic energy is ............... $J$
