A mass, m1 = 3.00 kg, resting on a frictionless horizontal table
is connected to a cable that passes over a pulley and then is
fastened to a hanging mass, m2 = 12.0 kg, as in Figure P4.25.
Find the acceleration of each mass and the tension in the cable.
Find the change in volume (in cubic cm) of an aluminum sphere
with an initial radius of 11 cm when the sphere is heated from
0.0 C to 140 C. The linear expansion coefficient of aluminum is
23 x 10-6 /C . A skier leaves the ramp of a ski jump with a
velocity of v = 18.0 m/s, = 21.0 above the horizontal, as in the
figure. The slope is inclined at 50.0 , and air resistance is
negligible. (Assume up and right are positive, and down and left
are negative.)Find the distance from the ramp to... A golf ball
is struck with a five iron on level ground. It lands 80.0 m away
4.60 s later. What was the magnitude and direction of the
initial velocity? (Neglect air resistance.) 1 m/s 2 above the
