Q1. A 4.5 kg block starts at rest and slides a distance d down a frictionless 32.0 degree incline, where it runs into a spring. The block slides an additional 0.17 m before it is brought to rest momentarily by compressing the spring, whose spring constant is 424 N/m. What is the value of d?
What is the distance between the point of first contact and the point where the block's speed is greatest?
Q2. A man drags a 72.0 kg crate across the floor at a constant velocity by pulling on a strap attached to the bottom of the crate. The crate is tilted 26 degrees above the horizontal, and the strap is inclined 68 degrees above the horizontal. The center of gravity of the crate coincides with its geometrical center, as indicated in the drawing. Find the magnitude of the tension in strap.
A flight attendant pulls her 72.0 N flight bag a distance of 282 m along a level airport floor at a constant speed. The force she exerts is 33.0 N at an angle of 52.0° above the horizontal.
What will transform in terms of the observable properties of the black hole as this process continues
Assume that the rod is held at rest horizontally and then released. (Throughout the remainder of this problem, your answer may include the symbol, moment of inertia of the assembly, whether or not you have answered the first part correctly.)
Discover the horizontal and vertical displacement
A person exerts a horizontal force of F = 175 N in the test apparatus shown in the drawing. (h = 0.25 m.) Find the horizontal force M that his flexor muscle exerts on his forearm.
The tension Tu in upper (taut) segment of the belt is 170 N, and flywheel has a clockwise angular acceleration of 1.67 rad/s2. Find out the tension in the lower (slack) segment of the belt.
What is rms speed of the atoms at temperature
Calculate the period T and the tension in the string F as a function of the angle. Compute the moment of inertia of this system for an axis that passes through the combined center of mass and is perpendicular to the plane of the rings.
When two tuning forks of 128 Hz and 149 Hz, respectively, are sounded simultaneously, how various beats per second are heard.
Determine magnitude of the force from the ground on each front wheel. what is magnitude of the duck's velocity.
What is the magnitude of an average acceleration of the ball
An old trick to find out if a train is coming is to put your ear on the rails of the track. Why is this more effective than just listening for the sounds the train makes in air.
