Question

Explain why, when catching a fast moving ball , the hands are drawn back while the ball is being brought to rest. ​

Answer 1

when catching a fast moving ball, the hands are drawn back while the ball is being brought to rest here momentum is used. conservation of momentum applied here . ball has some momentum when we catch our hands will also come in system ( hands+ ball) so, our hands get some velocity due to which our hands drawn back.

Answer 2

Answer:

Explanation:

Newton's second law states that the rate of change of momentum is directly proportional to the applied force

the hands are drawn back while the ball is being to rest therefore

• high velocity decreases to zero in a very short period of time
• acceleration decreases
• change of momentum is larger
