Physics
Jane is sitting on a chair with her lower leg at a 30.0° angle with respect to the vertical. You need to develop a computer model of her leg to assist in some medical research. If you assume that her leg can be modeled as two uniform cylinders, one with mass M1 = 17 kg and...

What velocity does the other glider have?

Physics
Two identical gliders on an air track are held together by a piece of string, compressing a spring between the gliders. While they are moving to the right at a common speed of 0.52 m/s, someone holds a match under the string and burns it, letting the spring force the gliders a...

A cannon on a railroad car is facing in a direction parallel to the tracks. It fires a 99 kg shell at a speed of 105 m/s (relative to the ground) at an angle of 60.0° above the horizontal. If the cannon plus car have a mass of 5.5 104 kg, what is the recoil speed of the ca...

Physics
A 0.15 kg baseball is pitched with a speed of 35 m/s (77 mph). When the ball hits the catcher's glove, the glove moves back by 2.7 cm (1.08 in.) as it stops the ball. Assuming a constant acceleration of the ball, what was the average force applied by the catcher's glove?

A 3.9 kg body is initially moving northward at 15 m/s. Then a force of 13 N, toward the east, acts on it for a time of 3.8 s. At the end of that time, what is the body's final velocity? (magnitude and direction)

Physics
A wheel's uniform angular acceleration is constant. Initially its angular velocity is zero. During the first 1.0 s time interval, it rotates through an angle of 92.0°. -Through what angle does it rotate during the next 1.0 s time interval? -Through what angle during th...
