In 2004 baseball player Adam Dunn hit the longest home run ever hit in Great American Ballpark in Cincinnati. He hit a homer which went 535 ft (163.1 m). In the following parts ignore any effects due to air resistance and assume the baseball lands at the same height it was hit.
Part A If he hit the ball at an angle of 60 degrees, what was the initial velocity of the baseball? Initial velocity =
Part B How long was the ball in the air? Time in air =
Part C What was the maximum height achieved by the baseball?
A 3.00 kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 2.20 m/s2, find out the force exerted by the rope on bucket of water.
Suppose a 65 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings and has a moment of inertia of 1850 kg m2. Calculate the angular velocity of the turntable
A rigid, well insulated container contains 10 kg of water. A motor connected to a paddle wheel is used to stir the water at a rate of 100 rad/s. How much toque does the motor need to supply (in N-m) in order for the water to heat up by 10?C in one..
find the energy in joules of the photons.
The horizontal surface is frictionless and the system is free from rest. Using energy concepts, determine the speed of m3 after it moves down a distance of 6.0 m.
