A ball with a mass of 29.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.29 m. Calculate the horizontal distance the ball would travel if the same spring were aimed 38.0o from the horizontal.
a popgun uses an ideal spring for which k=2000N/m. how high can the gun shoot a 5.0gram projectile
An RL circuit with L = 1.00 H and an RC circuit with C = 4.00 µF have the same time constant. What is this common time constant
A car is traveling 23 m/s when the driver sees a child standing in the road. He takes 0.8 s to react, then steps on the brakes and slows at 6.0 m/s2. Explain how far does the car go before it stops?
Find out the total work done on the car by the external forces.
An electron is initially at rest just outside a large copper surface that has the charge density of 1.20 x10-6 C/m2. How far has the electron moved in 1.07 x10-9 s if the field is uniform over this region.
Far in space, where gravity is negligible, a 485kg rocket traveling at 95.0m/s fires its engines. It shows the thrust force as a function of time. The mass lost by the rocket during these 30 s is negligible.
Sharon has a mass of 60 kg and is standing on a giant skateboard that is initially at rest and has a mass of 30kg. what is the speed of the skateboard
business equipment for a $5,000 loss, stock investment for a $7,000 loss, and her principal residence for a $16,000 loss. Presuming adequate income, explain how much of these losses may Joan claim on her 2011 return?
A string is wrapped around a disk of mass m = 1.7 kg and radius R = 0.08 m. Starting from rest, you pull the string with a constant force F = 7 N along a nearly frictionless surface. At the instant while the center of the disk has moved a distance..
