35:44 If a man falls on a cement floor made of hard soil, his speed will come to zero in such a short time. Due to which a strong opposing force can act on the person, the rate of change of momentum is very good. This force would seriously injure a man. Rather, falling onto the sand drives the feet deeper into the sand, expending less energy on the sand. So according to Newton's law, the sand only exerts less force on the feet. If a man falls on a sand dune with a soft landing, the man's chances of survival are high. Because loose sand or sand silt reduces the rate of dynamic transition. Due to which the person stops with a little force of sand and does not get hurt. That's why the sand becomes soft and slows down the speed of man.

*DOUBT!!* If there is an object whose mass is less but if its velocity is very high then its momentum will also be high and if we take another example then there is another object whose mass is very high but its velocity is very less then its momentum will also will be too much. So these two can be high momentum right?

The momentum which will transfer to the ground = Mass × Velocity `~ Mass = 10 kg `~ Velocity = ? By the third law of motion----- We have, V^2 = U^2 + 2AS ( $# Object are free falling from the height, so initial velocity will be 0 ) Now , V^2 = 0 + 2 × 10 ×80/100 V^2 = 16 V = 4 m/s Now ,,,, Momentum received by the floor from the object = Mass × Velocity = 10 kg × 4 m/s = 40 kg.m/s Sorry , for any mistake occurred. ..okh

I apologize for the mistake in my previous response. Here's the correct solution: The change in momentum of the hockey ball is given by the formula: Change in momentum = Final momentum - Initial momentum The momentum of the ball before it was struck by the hockey stick is given by: Initial momentum = m x u where m is the mass of the ball and u is its initial velocity. Substituting the given values, we get: Initial momentum = 0.2 kg x 10 m/s = 2 kg m/s The momentum of the ball after it was struck by the hockey stick is given by: Final momentum = m x v where v is the final velocity of the ball. Substituting the given values, we get: Final momentum = 0.2 kg x 5 m/s = 1 kg m/s Therefore, the change in momentum of the hockey ball is: Change in momentum = Final momentum - Initial momentum = 1 kg m/s - 2 kg m/s = -1 kg m/s The negative sign indicates that the direction of the change in momentum is opposite to the direction of motion of the ball. The force applied by the hockey stick can be calculated using the formula: Force = Change in momentum / Time Since we don't know the time of impact, we cannot calculate the force applied by the hockey stick.
