Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

Question

An engineering student throws a calculator straight up to a COVID-quarantined
friend, who is leaning out a window 5.12 m above. The friend catches the calculator
1.43 s later and immediately sanitizes it and her hands.

Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. c) Find the average force exerted by the club on the ball. d) Find the average shear deformation of the club's 0.800 m long and 1.00 cm diameter steel shaft.

Problem 4: Two tractor-trailer trucks are driving side-by-side on interstate 40. The one on the left hugs the right side of the lane, and the one on the right hugs the left side of the lane, so that the two are almost touching. A physics student driving behind witnesses the event, and realizes that the time is ripe for a daring experiment. With the alacitry of the Lone Ranger, she leaps from her car onto the back of one of the trucks, and climbs on the roof. The student has in her left pocket a 9 Volt Eveready battery, and in her right pocket she carries two wires. The writing on one side indicates that the battery has a capacity of 550 mAh. She pauses briefly and wonders what this could mean, before refocusing her attention on the task at hand. She quickly connects the negative terminal of the battery to one truck, and the positive terminal to the other, in order to charge the trucks. (a) If the distance between the trucks is 5 nm, estimate how much charge will be on each of the…
