A small block is released from rest at the top of a frictionless incline. The block travels a distance 0.263 m in the first second after it is released. How far does it travel in the next second?
The coefficient of kinetic friction between the block and incline is = 0.45. The mass of the spring is negligible.
The Moon moves noticeably on the celestial sphere over the space of a single night. To show this, calculate how long it takes the Moon to move through an angle equal to its own angular diameter (0.5 degrees) against the background of the stars. Gi..
A force vector has a magnitude of 594 newtons and points at an angle 37o of below the positive x axis. What are (1) the x scalar component and (2) the y scalar component of the vector.
A 12 kg runaway grocery cart runs into a spring with spring constant 300 N/m and compresses it by 70 cm.What was the speed of the cart just before it hit spring.
Two capacitors give an equivalent capacitance of 9.00 pF when connected in parallel and an equivalent capacitance of 1.95 pF when connected in series. What is the capacitance of each capacitor?
A cord connected at one end to a block which can slide on an inclined plane has its other end wrapped around a cylinder resting in a depression at the top of the plane . Determine the speed of the block after it has traveled 1.80 along the plane, ..
A 78 kg circus performer jumps from a 4.20 m height onto a trampoline and stretches it downward 0.3m. suppose that the trampoline obeys Hooke's law.
A basketball player makes a jump shot. The 0.600 kg ball is released at a height of 2.00 m above the floor with a speed of 7.20 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.20 m/s Find the work done on the ball by air ..
A parallel plate capacitor has plates of area 2.0x10^-3 m^2 and a plate separation of 1.0x10^-4 m. Determine the capacitance of this system if air fills the volume between the plates.
