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?
How high up a frictionless incline could mass climb? How far could the mass skid on a level table with a static mu of 0.70 and a kinetic mu of 0.50.
If 20 grams of hot water at 80°C is poured into a cavity in a very large block of ice at 0°C, what will be the final temperature of the water in the cavity? How much ice should melt in order to cool the hot water down to this temerature.
An electron has an initial velocity of 3.50 106 m/s in the x direction. It enters a uniform electric field = (400 N/C) , which is in the y direction. (a) Find the acceleration of the electron.
A gun shoots bullets that leave the muzzle with a speed of 338 m/s. If a bullet is to hit a target 104-m away at the level of the muzzle, the gun should be aimed at a point above the goal.
The press box at a baseball park is 30 ft above the ground. A reporter in the press box looks at an angle of 18 degrees below the horizontal to see second base. What is the horizontal distance from the press box to second base.
