A body of radius 0.323 m and mass 1.64 kg is rolling smoothly with speed 3.47 m/s on a horizontal surface. It then rolls up a hill to a maximum height 2.64 m. What is the bodys rotational inertia abou
1) A frog in a hemispherical pod finds that he just floats without sinking in a fluid od density 1.35 g/cm^3. if the pod has a radius of 6.00 cm and negligible mass, what is the mass of the frog?

A 520 g air-track glider attached to a spring with spring constant 10 N/m is sitting at rest on a frictionless air track. A 170 g glider is pushed toward it from the far end of the track at a speed of
A car moved 20 km East and 60 km West in 2 hours. What is its average velocity?-Velocity is a vector with both magnitude and direction.The average velocity is the magnitude of the final displacement d
Calculate vrms for a neon atom in the room youre in (whose temperature is probably about 293 K). (Reminder: Atomic masses can be found in the front of your textbook)
?? m/s-vrms=(3RT/M)^0.5=603.9m/s

thanks for answering! :D-Important to History:
The Pythagorean Theorem was one of the first times in human history that people could calculate a length (or distance) using only outside ( and seemingl
A ball with a radius of 15cm rolls on a level surface, and the translational speed of the center of mass is 0.20m/s.What is the angular speed about the center of mass if the ball rolls without slippin
It flows in the direction opposite the direction of electrons. since it has a direction and magnitude shouldnt it be a vector quantity??-While this is an excellent question and I can understand why yo
It is impossible to accelerate to the speed of light, as your mass would become infinite.However, there may be ways to warp space-time in order to travel faster than light without reaching c.For examp
a) What is its angular acceleration, assuming the acceleration is uniform?
b) How many revolutions does the engine make during this time?
*These questions are driving me insane!-change in angular s
If a projectile it sent with an initial velocity u from a level surface and an angle α write an expression showing the time taken for the projectile to reach the ground, t and another expression combi
A source of electromagnetic waves radiates power uniformly in all directions at a single frequency. At a distance of 5.50 km from the source, a detector measures the intensity of the wave to be 39.0 μ
A tall cylinder with a cross-sectional area 11.0 cm^2 is partially filled with mercury; the surface of the mercury is 4.00 cm above the bottom of the cylinder. Water is slowly poured in on top of the
