Answers
b) It can be answer acc. to newton 3rd law of motion i.e. for every action there is an equal and opposite reaction
when an athelete jump high , he may apply a large force Answer and Explanation:
a) when the bus is moving our body although at rest but it is also moving forward with respect to the other object on the street
so when the breaks are applied , bus stops but our body wants to remain in forward motion so it an inertia of motion comes into play and our body fall forward .
b) In a high jump athletic event, the athletes are made to fall either on a cushioned bed or sand bed. This is to increase the time of the athlete's fall to stop after making the jump. This decreases the rate of change of momentum and hence, the force. As a result, the athlete does not get injured.
