A frictionless pulley has the shape of a uniform solid disk of mass 4.00 kg and radius 28.0 cm. A 3.90 kg stone is attached to a very light wire that is wrapped around the rim of the pulley , and the stone is released from rest. As it falls down, the wire unwinds without stretching or slipping, causing the pulley to rotate. How far must the stone fall so that the pulley has 2.70 J of kinetic energy?
When she lets go of the rope her initial velocity is 2.25 m/s at an angle of 35 degrees above the horizontal. If she is in flight for .616 s, explain how high above the water was she when she let go of the rope?
When a 5.5 cm long pencil is arranged perpendicular to a convex mirror's optical axis at a distance of 29 cm from the mirror, its image is 2.8 cm tall. (a) What is the mirror's focal length (include sign if negative)? (b) How tall is the pencil's ..
An electron is at the origin. (a) Calculate the electric potential VA at point A, x = 0.160 cm. V (b) Calculate the electric potential VB at point B, x = 0.170 cm. V What is the potential difference VB - VA? V
What is the coefficient of kinetic friction between the table and floor.
An unstrained horizontal spring has a length of 0.34 m and a spring constant of 290 N/m. Two small charged objects are attached to this spring, one at each end. The charges on the objects have equal magnitudes.
A car makes a round trip for 100m in 10 seconds. What is the average velocity?
A spring with spring constant 14 hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 3.0 and released. The ball makes 17 oscillations in 16 seconds. What is it the mass of ball.
A 2500-kg sport utility vehicle travelling at 92 km/h can be stopped in 0.25 s if it hits a concrete wall. Assume a 60 kg person was in the car that hit this wall. The velocity of the person equals that of the car both before and after the crash, and..
Two meteoroids are heading for earth. Their speed as they cross the moon's orbit is 2.3 km/s. The second meteoroid misses for earth by 2680 km. What is its speed at its closest point.
You may also assume that v_0 gg sqrt{2gL}, so that the change in hammer's gravitational potential energy, as it drives the nail into the block, is insignificant.
A car is traveling 17 m/s when the driver sees a child standing on the road. He takes 0.8 s to react, then steps on the brakes and slows at 7.5 m/s2. How far does the car go before it stops.
