Why shockers are provided in automobile vehicles?
a bullet of mass 20g is horizontally fired with a velocity of 150m/s frm a pistol of mass 2kg. What is the recoil velocity of the pistol?
Find the initial velocity of the car which is stopped in 10 sec by applying brakes .The retardation due to brakes is 2.5m/sec sq.....
Define: INERTIA
A bullet fired from a gun makes a clean whole in a window whereas a stone pebble thrown brakes the whole window.why?
How much momentum will a dumbbell of mass 10 Kg transfer to the floor if it falls from a height of 80 cm? Take its downwards acceleration to be 10 m/s2?
can someone plz tell me the derivations of equations of motions without graph ..
why chinaware is wrapped in straw while transportation?
a bullet of mass 10 g is fired from a rifle with a velocity of 800 m/s . after passing through a mud wall 180cm thick, the velocity drops to 100m/s. calculate the average resistance of the wall.
A gunman gets a jerk on firing a bullet.why??
action and reaction forces do not balance each other. why?
Few examples of balanced and unbalanced force?
why is it difficult to balance our body when we accidentally step on a peel of banana give reasons
An object of mass 1 kg travelling in a straight line with a velocity of 10 m s−1 collides with, and sticks to, a stationary wooden block of mass 5 kg. Then they both move off together in the same straight line. Calculate the total momentum just before the impact and just after the impact. Also, calculate the velocity of the combined object.
An object of mass 100 kg is accelerated uniformly from a velocity of 5 m s−1 to 8 m s−1 in 6 s. Calculate the initial and final momentum of the object. Also, find the magnitude of the force exerted on the object.
