A race car starts from rest on a circular track of radius 450 m. The car's speed increases at the constant rate of 0.900 m/s2. At the point where the magnitudes of the centripetal and tangential ac
A juggler throws a bowling pin straight up with an initial speed of 8.00. How much time elapses until the bowling pin returns to the juggler's hand?
Question: Determine the object position for which the resulting image is upright and seven times the size of the object.
A 295 ball is tied to a string. It is pulled to an angle of 5.40 and released to swing as a pendulum. A student with a stopwatch finds that 16 oscillations take 11.5 .
A brass ring of diameter 10.00 cm at 19.7°C is heated and slipped over an aluminum rod of diameter 10.01 cm at 19.7°C. Assume the average coefficients of linear expansion are constant.
A rope of negligible mass is wrapped around a 225-kg solid cylinder of radius 0.400 m. The cylinder is suspended several meters off the ground with its axis oriented horizontally, and turns on that
An electric field of approximately 100 v/m is often observed near the surface of Earth. if this were the field over the entire surface, what would be the electric potential of a point on the surfac
A 1300 {rm kg} wrecking ball hangs from a 20 {rm m}-long cable. The ball is pulled back until the cable makes an angle of 24.0^circle with the vertical. By how much has the gravitational potential
A bungee jumper, whose mass is 98 kg, jumps from a tall platform. After reaching his lowest point, he continues to oscillate up and down, reaching the low point two more times in 9.0 s. Ignoring ai
A 0.12-kg ball is placed in a shallow wedge with an opening angle of 120°, as shown in the figure. For each contact point between the wedge and the ball, determine the force exerted on the ball
Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go-round's rim. What is the final angular speed of the merry-go-round?
In the drawing, the weight of the block on the table is 452 N and that of the hanging block is 215 N. Ignore all frictional effects, and assuming the pulley to be massless.
Four charged particles are placed at the locations (0,0,a),(0,0,-a),(0,a,0),(0,-a,0) with charge q,5q,-3q,and -3q at each location. Find a simple approximation for the potential far away from the o
What is the terminal speed for an 82.0 skier going down a 43.0 snow-covered slope on wooden skis = 0.060?
A 45.0 kg girl is standing on a 165 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a co
A car slows down with an acceleration that has a magnitude of 3.4 m/s2. While doing so, it travels 113 m in the +x direction and ends up with a velocity of +4.3 m/s. What was the car's initial velo
A 180 , 48.0-cm-diameter turntable rotates on frictionless bearings at 70.0 . A 15.0 block sits at the center of the turntable. A compressed spring shoots the block radically outward along a fricti
When you weigh yourself on good old terra firma (solid ground), your weight is 135 lb. In an elevator your apparent weight is 118 lb. What are the direction and magnitude of the elevator's accelera
How much would a 80.0 kg person weight (a) on Mars, where the acceleration of gravity is 3.93 m/s2, and (b) on Earth's Moon, where the acceleration of gravity is 1.63 m/s2?
A force acting on an object is approximated as F = 4 sin (100pt) N from t = 0 to t = 10 ms. Calculate the impulse on the object
If a material has an index of refraction 2.35, what is the speed of light in this material. Consider the speed of light in the vacuum c = 300000000 m/s. Express the answer with one decimal place.
A 172 ball is tied to a string. It is pulled to an angle of 3.40 and released to swing as a pendulum. A student with a stopwatch finds that 16 oscillations take 16.5 .
The speed of light in a material is 0.41 c. What is the critical angle of a light ray at the interface between the material and a vacuum?
