In a tug-of-war contest, two men pull on a horizontal rope from opposite sides. The winner will be the man who
exerts greater force on the rope
exerts greater force on the ground
exerts a force on the rope which is greater than the tension in the rope
makes a smaller angle with the vertical
A particle of mass $2\, kg$ is initially at rest. A force acts on it whose magnitude changes with time. The force time graph is shown below. The velocity of the particle after $10\, s$ is ......... $ms^{-1}$
Swimming is possible on account of
A particle of mass $m$ is moving with a uniform velocity $v_1$. It is given an impulse such that its velocity becomes $v_2$. The impulse is equal to
A stone is dropped from a height $h.$ It hits the ground with a certain momentum $P.$ If the same stone is dropped from a height $100\%$ more than the previous height, the momentum when it hits the ground will change by ........... $\%$
Two billiard balls each of mass $0.05\; kg$ moving in opposite directions with speed $6\; m/s$ collide and rebound with the same speed. What is the impulse imparted to each ball due to the other?
