7. A baseball pitcher can throw a 132 km/h (82 mph) curve ball that rotates about 6.0x102 rpm. What is the angular velocity of the thrown ball? The pitcher's throwing motion lasts about 0.15 s, and the moment of inertia of the ball is 8.0x10-5 kg-m2. What average torque did the pitcher exert on the ball? 9. A bicycle is clamped upside down on a workbench for the bicycle repair woman to repair a front wheel axle. She gives the front wheel a spin with her hand, and the wheel rotates at 5.0 rev/s. What is the angular velocity of the wheel? If the moment of inertia of the wheel is 0.060 kg. m², what angular impulse did the repair woman give the wheel?

where is the circuit diagram ?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
