Q. A baseball is thrown horizontally at the catcher, who is 60.0 ft away. It is thrown with a velocity of 87.5 mph. How far does the baseball fall during this pitch?
Q. How do you investigate the factors that conclude the force of friction between the wooden block and the surface on which it is resting?
A 56.0 kg ice skater spins about a vertical axis by her body with her arms horizontally outstretched, making 1.50 turns each second. The distance from one hand to the other is 1.5 m . Biometric measurements indicate that each hand typically makes ..
select the quantity that has changed(velocity or speed) for a car that travels north at 88 km/h and then turns east while continuing to move at 88 km/h. define your answer.
what force is needed to pull a 150 pound sled along a horizontal surface? The coeficient of kinetic friction is 0.10 and the sled is pulled by a rope that makes the angle of 0 degree with the horizontal. There is no acceleration.

A 1800 kg pile driver is used to drive a steel I-beam into the ground. The pile driver falls 6 m before coming into contact with the top of the beam, and it drives the beam 14.0 cm farther into the ground before coming to rest.
If a car traveling at 62 km/h will skid 22 m as its brakes lock, how far will it skid if it is traveling at 120 km/h when its brakes lock.
The difference in potential between the accelerating plates of a TV set is about 26000 V. If the distance between these plates is 1.5 cm, find out the magnitude of the uniform electric field in this region.
Coherent light with wavelength 601 passes through two very narrow slits, and interference pattern is observed on a screen a distance of 3.00 from the slits.
A major-league catcher gloves a 85 mi/h pitch and brings it to rest in 0.17m. If the force exerted by the catcher is 803 N, what is the mass of the ball.
A wooden raft has a mass of 67 kg. When empty it floats in water (density 1000 kg/m3) with 51 percent of its volume submerged. What mass of sand can be put on the raft without it sinking.
A 180, 48.0 cm-diameter turntables rotate on frictionless bearings at 70.0. A 15.0 block sits at the center of turntable. A compressed spring shoots the block fundamentally outward along the frictionless groove in the surface of the turntable.
