Out of idle speculation, you drop a metal ball from a height of 2 yards onto a sample cute from a plastic sheet. (You are an old-fashioned engineer and can have no truck with units such as meters.) You observe that the plastic sheet punctures in a ductile fashion, leaving a hole roughly the size of the ball. You find that if the same metal ball is dropped onto another sample of the same plastic sheet from a height of 4 yards, the sample shatters in a brittle manner. How would you explain these observations?

A ball, dropped onto a hard floor from a height of 2 meters, bounces to a height of 1.8 meters, 90% of the initial height. Each subsequent bounce is 90% the height of the previous one. Find the total distance the ball travels up and down (i.e. after the first collision with the ground it has traveled 2 meters down and 1.8 meters up, giving a total distance of 3.8 meters).

A soft tennis ball is dropped onto a hard floor from a height of 1.70 m and rebounds to a height of 1.17 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor. m/s (b) Calculate its velocity just after it leaves the floor on its way back up. m/s (c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms. m/s2 (d) How much did the 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...

a ball is thrown up onto a roof, landing 3.60 s later at height h = 25.0 m above the release level. The ball's path just before landing is angled at ? = 64.0?with the roof. (a) Find the horizontal distance d it travels. (Hint: One way is to reverse the motion, as if it is on a video.) What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's initial velocity?

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.

1. You drop a wooden cork from a height of a few feet above the water. The positive direction is defined as upwards. While the cork is fully submerged and moving downward (after it has fully submerged in the water), the sign of the cork's velocity is ___ ["positive", "negative", "zero"] , and the sign of the cork's acceleration is ______ ["positive", "negative", "zero"] 2. You drop a wooden cork from a height of a few feet above...

While out on your 3rd floor apartment balcony, you notice someone drop a 8.0 kg ball from rest from the roof of the 5 story building across the street. You know that the two identical buildings are 34 m apart, and have floors that are 5.0 m tall. The first floor is at ground level. m = 8.0 kg d = 34 m h = 5.0 (a) determine the magnitude of the angular momentum of the ball, in kilogram meters...

A punter drops a ball from rest vertically 1 meter down onto his foot. The ball leaves the foot with a speed of 27 m/s at an angle 52° above the horizontal. What is the impulse delivered by the foot? (Use 0.41 kg for the mass of the ball. Assume the punter faces the +x-direction and that the +y-direction is upward. Enter the impulse in kg · m/s and the direction in degrees counterclockwise from the +x-axis.)

Drop an object from a certain height and measure the time it takes to reach the ground. Repeat at least 5 times and average the time data. Calculate this height by using the free fall formulas(this is the experimental height). Measure the height by using a measuring tape ( this is the Real height). Report Include a word description of your experiment. A drawing of your set up. Physics formulas used. Finish with a % error of the height. %...
