Q. A 250 kg car starting from rest is pushed 30m. While the car reaches 30m, it's travelling at a speed of 12 m/s and it encounters 52N of friction. What is the acceleration of car and what is the force of the push on the car?
Q. The crest of the second hill is circular, with a radius of r = 35m. Avoid friction and air resistance. What must be the height h of the first hill so that skier just loses contact with the snow at the crest of the second hill?
On a dry day, just after washing your hair to remove natural oils and drying it in detail, run a plastic comb through it. Small bits of paper will be attracted to the comb. Describe why.
If the car is going 55m/s, how many meters will it travel before it stops? How many meters will it takes to stop car going twice as fast.
What is the distance between the centers of the two slits? Describe answer in m.
An ice cube of mass ma and specific heat Ci is initially at temperature T1, where T1 is less than 273K. If L is the latent heat of fusion of water, and the specific heat of water is Cw, how much energy is needed to convert the ice cube to water at ..
A loudspeaker of mass 20 is suspended a distance of 2 below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of 2.90.
Four identical masses of mass 710 kg each are placed at the corners of a square whose side lengths are 15.0 cm. What is the magnitude of net gravitational force on one of the masses, due to the other three.
What is coefficient of friction between chair and floor
Travelling at a speed of 17.10 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.740. What is the speed of the automobile after 1.81 s have el..
A 13g bullet traveling 223m/s penetrates a 2kg block of wood and emerges cleanly at 160 m/s. If the block is stationary on the frictionless surface when hit, how fast (m/s) does it move after the bullet emerges.
A 60kg boy and a 45 kg girl use an elastic rope while engaged in a tug-of-war on a frictionless icy surface. If the acceleration of the girl toward the boy is 2.3 m/s2, find the magnitude of the acceleration of the boy toward the girl.
Dan is gliding on his skateboard at 2m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 5.00 kg.
A pencil (mass 5.8g and length 8.3cm) is at first balanced so that it is sitting vertically on a flat table. If the pencil then falls, find its angular velocity just before it strikes the tabletop. Assume that the mass of the pencil is distributed un..
