In A Skating Stunt Known As Crack The Whip A Number Of Skaters Hold Hands And Fo 1

In a skating stunt known as “crack-the-whip,” a number of skaters hold hands and form a straight line. They try to skate so that the line rotates about the skater at one end, who acts as the pivot. The skater farthest out has a mass of 69.0 kg and is 6.0 m from the pivot. He is skating at a speed of 6.60 m/s. Determine the magnitude of the centripetal force that acts on him.

In A Slow Pitch Softball Game A 0 200 Kg Softball Crossed The Plate At 17 0 M S

In a slow-pitch softball game, a 0.200 kg softball crossed the plate at 17.0 m/s at an angle of 35.0° below the horizontal. The batter hits the ball toward center field, giving it a velocity of 46.0 m/s at 30.0° above the horizontal.(a) Determine the impulse delivered to the ball.1Your response differs from the correct answer by more than 10%. Double check your calculations. N·s (magnitude)2Your response differs from the correct answer by more than 10%. Double check your calculations.° (above the horizontal)(b) If the force on the ball increases linearly for 4.00 ms, holds constant for 20.0 ms, then decreases linearly to zero in another 4.00 ms, what is the maximum force on the ball?3 N (magnitude)4° (above the horizontal)

In A Snail Race You Time How Fast Your Snail Is Slithering

In a snail race, you time how fast your snail is slithering. It is slow so he has devised a scheme to use interference of light to help him measure it. Two parallel thin glass plates are oriented vertically as seen below. The plate on the right moves to the right at a constant speed “v”. When 500 nm light is incident normal to the plates from the left you observe the light to be strongly reflected every 10 seconds. What is the speed of the glass plate on the right?
