Question

A cricket ball of mass 70 g moving with a velocity of 0.5 m/s is stopped by a player in 0.5 s. What is the force applied by the player to stop the ball?​

Answer 1

Answer:

mass of ball=70g=0.07 kg

velocity of ball=0.5 m/s

impulse=rate of change of momentum=m(v-u)=0.07(0-0.5)=0.07×-0.5=-0.035 Ns

impulse =force ×time

-0.035=force ×0.5

-0.035÷0.5=force applied

-0.07 N=force applied

Answer 2

Merchants also contributed to the Renaissance by making basic education more widespread, especially in math and accounting. The growth of the merchant class meant that a lot more people needed to learn, read, count, and do basic math, so they could keep track of their sales.
