Impulsive Force

Impulse Force||Impulse||Impulse Momentum Theorem

After calling a wall of 3 m heigh a mass of weight W drops himself to the ground. If his body comes to a complete stop in 0.15 s . After his feet touch the ground, calculate the average impulsive force in the vertical direction exerted by ground on his feet.

An impulsive force gives an initial velocity of- 1.0 m s^(-1) to the mass in the unstretched spring position [sec Fig. 16.2]. What is the amplitude of motion ? Give x as a function of time t for the oscillating mass. Given m=3 kg and k=1200 Nm^(-1) .

A particle of mass 1 kg is moving with a velocity of 200 m/s. An impulsive force of 4 s duration acts on the particle in a direction opposite to its motion. The force fluctuates a little bit around 40 N magnitude and then it dies out in next 4s showing small fluctuations. An oscilloscope records the force as shown. The two oscillating components in the graph are identical except that one is mirror image of the other. Find the magnitude of velocity of particle after the force stops acting.

Choose the pairs of quantities which have same dimensions : Impulse, force, work, momentum, moment of force, tension.

The following problems illustrate the effect of a time-dependent force of a large average magnitude which acts on a moving object only for a short duration. Such forces are called 'impulsive' forces. According to the impulse-momentum theorem, impulse delivered to a body is equal to the change of linear momentum of the body. A ball of mass 250 g is thrown with a speed of 30 m//s . The ball strikes a bat and it is hit straight back along the same line at a speed of 50 m//s . Variation of the interaction force, as long as the ball remains in contact with the bat, is as shown in Fig. Maximum force exerted by the bat on the ball is
