Consider a cricket ball and a tennis ball (each with the same mass). If you drop the tennis ball and cricket ball from the same height (ignore air resistance), explain why it hurts more when the cricket ball lands on your foot compared to the tennis ball.

Expert Solution

solution:

here if both have same mass then both have same velocity and momentum.and both have same force impact on foot.but if tennis ball and cricket ball material is different and tennis ball is made from lighter material compare to cricket ball material then there is volume of tennis ball increase to make same ball as cricket ball.

so if volume of tennis ball is increase then net force contact area of tennis balll is more then cricket ball contact area to foot. but cricket has same amount of force with less contact area with foot.so cricket ball make more pressure on foot and it heats more .( pressure = force / areaa)

here force is equal, because momentum is equal. but ressure is different on foot.because contact area is different on foot due volume are different.so cricket ball has small volume and small contact area.so pressure by cricket ball is more then pressure of tennis ball on foot.so it is more hurt on foot

The request business is planning to manufacture a new type of tennis ball. Each tennis ball would sell for 3.75 and would require 1.75 in variable costs. In addition, annual fixed costs associated with the project would total 64,000. (A) use the contribution margin approach to calculate: (1) the breakeven point in units (2) the breakeven point in dollars (B) determine the operating income or loss at a sales volume of 30,000 tennis balls. (C) determine the number of tennis...

A man is playing tennis game. He hits a stationary ball of mass 50 g with his racquet. Interpret the energy conversions taking place when he hits ball with racquet. The average force acting on it is 600 N, so that the ball moves with a velocity of 60 m/s .Can you predict the time of hit of the ball when it leaves the racquet using given data? How can you find the change in kinetic energy of moving ball?...

You drop a ball from a window on an upper floor of a building and it is caught by a friend on the ground when the ball is moving with speed vf. You now repeat the drop, but you have a friend on the street below throw another ball upward at speed vf exactly at the same time that you drop your ball from the window. The two balls are initially separated by 57.6 m. (a) At what time do...
