Answer 1

Q4.)A cricket player moves his hands backwards while catching a ball in order to decrease the acceleration of the ball and catch it without applying enough pressure.

Q5) Force=mass x acceleration

Now, compare both situations in terms of force...

2 Kg mass at 5m/s²

Force=2 x 5 =10N

And, 4 kg mass at 2m/s²

Force= 4 x 2 =8 N

Hence, accelerating at 2 kg mass at 5m/s² will require a greater force.
