(Will give brainliest) A hoop (MR2), a disk (1/2MR2) and a sphere (2/5MR2) are start at the top of a ramp of length 2.5m making an angle of 12˚ with the horizontal.
1.Which objects gets to the bottom the fastest?
2.Which object has the greatest kinetic energy at the bottom?
3.Calculate the translational velocity for each object.

When someone slams her books on a table the kinect energy is transferred into vibrations that travel to your ears as sound waves which statement describes the movement of those waves

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
