A 13 g bullet traveling 217 m/s penetrates a 2 kg block of wood and emerges cleanly at 153 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
a skier of mass 100 kg, starts from rest as the top of a frictionless incline of height 20 m, how far does she travel on the horizontal surface before coming to rest
In a college homecoming competition, eighteen students lift a sports car. Though holding the car off the ground, each student exerts an upward force of 390 N. What is the mass of the car in kilograms? What is its weight in pounds.
The weight of passengers on a roller coaster increases by 51 percent as the car goes through a dip with a 39 radius of curvature.What is the car's speed at the bottom of the dip.
An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 3.18 cm. If its x-coordinate 2.95 s later is ?5.00 cm, what is its acceleration?
A mass of 125g is suspended from a spring of a spring constant of 38N/m. When this mass is pulled down 3mm and set in oscillation, what is the period and frequency of the oscillation? How different would be both, the period and frequency, if the m..
When subject to a steady acceleration of 0.800 g, the object must be located 0.600cm from its equilibrium position. Find the force constant required for the spring.
Regarding the Earth and a cloud layer 750 m above the Earth as the "plates" of a capacitor, calculate the capacitance. Assume the cloud layer has an area of 1 km2 and that the air between cloud and ground is pure and dry.

The spaceship Intergalactica lands on the surface of the uninhabited Pink Planet, find the acceleration due to gravity on the Pink Planet\'s surface by means of a simple pendulum of length 1.06 m
At t = 0, a particle leaves the origin with the velocity of 9 m/ s in the positively direction and moves in the x y plane with a constant acceleration of (2.0i - 4.0j) m/ s2. At the instant the x coordinate of the particle is 15m, what is the spee..
A 1500 kg car carrying four 87kg people travels over a rough "washboard" dirt road with corrugations 4.40 m apart which causes the car to bounce on its spring suspension. The car bounces with maximum amplitude while its speed is 19km/h. The car now s..
