What is the tangential acceleration of a bug on the rim of a 12.0 in. diameter disk if the disk moves from rest to an angular speed of 78 revolutions per minute in 4.0 s? When the disk is at its final speed, what is the tangential velocity of the bug? One second after the bug starts from rest, what are its tangential acceleration, radial acceleration, and total acceleration(with the degree)
Iif the collision is perfectly elastic, what is the ball's speed immediately after the collision? Illustrate what is the maximum compression of the spring?
A 1.0--tall vertical tube is filled with 20o water. A tuning fork vibrating at 574 is held just over the top of the tube as the water is slowly drained from the bottom.
Before going into orbit, an astronaut has a mass of 55 kg. While in orbit, a measurement determines that a force of 100 N causes her to move with the acceleration of 1.90 m/s2. To regain her original weight, must she go on a diet or start eating m..
Heat is another word for thermal energy. Dissimilar materials at the same temperature can contain different amounts of heat.
How to find out the magnitude of the acceleration
The difference in piezometric pressure, pz,A – pz,B. Express both answers in kPa and pressure differences pA - pB.
A 40-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, kinetic energy decreases to 240J from 470J. How high does she rise during this interval? Avoid air resistance.
Vector A has a magnitude of 9.10 units and makes an angle of 54.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods find the following.
An oil rig in the gulf is held at its designated drilling location by 3 tugboats. tugboat A oulls with 42000 N straight in the east direction. Tugboat B pulls at an angle of 50 degrees north of west. tugboat C pulls 25 degress west of south. draw ..
A 60.0 resistor is connected in parallel with a 116 resistor. This parallel group is connected in series with a 20.0 resistor. The total combination is connected across a 15.0 V battery.
what is the maximum weight of the crate that the system can support? What is the angle needed for equilibrium.
The burning of gasoline in a car releases about 3 × 10^4 kcal/gal. If a car averages 43 km/gal when driving 90 km/h, which requires 20 hp, what is an efficiency of the engine under those conditions.
