A basketball leaves a player's hands at a height of 2.20m above the floor. The basket is 3.05m above the floor. The player likes to shoot the ball at a 38.0 degree angle.
If the shot is made from a horizontal distance of 5.10m and must be accurate to plus/minus 0.23m (horizontally) what is the range of initial speeds allowed to make a basket?
A cart of mass M = 1.6 kg can roll without friction on the level track. A light string draped over a light, frictionless pulley connects the cart to a hanger with mass m = 0.7 kg.
Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern is observed on a screen that is 2.56 m from the grating. In the first-order spectrum, maxima for two different wavelengths are separ..
A positive image distance means that image is formed on the side of the lens from which the light emerges.
A bullet of mass 4.3 g is fired horizontally into a 8.60 kg wooden block at rest on horizontal surface. The coefficient of kinetic friction between block and surface is 0.13.
A mass of 1.7kg stretches a vertical spring 0.313 m. If the spring is stretched an additional 0.13m and released, how long does it take to reach (new) equilibrium position again.
Petrus takes a cold glass of cola from fridge. He puts 3 cubes of ice into it. He laeves the glass on a table in a warm room for 5 minutes. He notices that the ice cubes have become smaller. The outside of the glass is now wet. What is the reason ..
A 3.3 block of wood sits on a table. A 3.0 bullet, fired horizontally at a speed of 480, goes completely through the block, emerging at a speed of 200 .What is the speed of block immediately after the bullet exits.
Two boats are initially separated by distance d and head directly toward one another. The skippers of the boats want to arrive at the same time at the point that is halfway between their starting points.
At one instant a bicyclist is 35.0m due east of a park's flagpole, going due south with a speed of 20 m/s. Then, 19 s later, the cyclist is 60.0 m due north of the flagpole, going due east with the speed of 11 m/s. For the cyclist in this 19s inte..
