spike has

A volleyball is spiked so that it has an initial velocity of 15 m/s directed downward at an angle of 55^(@) below the horizontal. What is the horizontal component of the ball's velocity when the opposing player fields the ball?

List out the difference between spike and spadix.

In the arrangements shown in the figure there is friction only between the light string and the sharp spike at the point P. when the blocks are in motion, the tensions in the vertical and horizontal sections of the string are 4N and 3N respectively. The co-efficient of friction between the string and the spike is equal to

A hammer weighing 3 kg moving with a velocity of 10ms^(-1) strikes against the head fo a spike and drives it into a block of wood. If the hammer comes to rest in 0.025 s, find (i) the impulse and (ii) the average force on the head of the spike.
