Q. A 48.0 ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.50 turns each second. The distance from one hand to the other is 1.50. Biometric measurements indicate that each hand typically makes up about 1.25 of body weight.
a. What horizontal force must her wrist exert on her hand?
b. Express the force in part (a) as a multiple of the weight of her hand.
What is an acceleration of the particle at the instant
A 200 g block is pressed against a spring of force constant 1.40 kN/m until the block compresses the spring 10 cm. The spring rests at the bottom of a ramp inclined at 60.0 degrees to the horizontal.
A child's toy consists of a piece of plastic attached to a spring. The spring is compressed against the floor a distance of 2.0 cm and released. If the spring constant is 85 N/m, what is the magnitude of spring force acting on the toy at the moment i..
What is the direction of the object's acceleration after it is free. What is the magnitude of the objects acceleration.
A disk of radius has a total charge uniformly distributed over its surface. The disk has negligible thickness and lies in the xy plane. What is the electric potential V (z) on z axis as a function of z, for z>0.
A certain engine can exert 75,000 kg m/sec/sec of force. Assuming that all the force is used to accelerate the vehicle on which the engine is mounted, how fast would the vehicle accelerate assuming that it masses 5,000 kg? Neglect friction/air res..
What is the velocity of 5.5kg object with a force of 2.5N while it reaches 6.0 meters, assuming the velocity at zero meters is zero.
A 13g bullet traveling 221 m/s penetrates a 2 kg block of wood and emerges cleanly at 160 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
Assume your car was modified so you could travel through space. At a velocity of 65 mi/hr, and driving non-stop, how long would it take for you to get to.
The escape speed from a very small asteroid is only 26 m/s. If you throw a rock away from the asteroid at a speed of 39 m/s, what will be its final speed.
A train at a constant 75 km/h moves east for 48 min, then in a direction 61.0° east of due north for 11min, and then west for 67 min.
