Asmall lead ball, attached to a 1.25-m rope, is being whirled in a circle that lies in the vertical plane. the ball is whirled at a constant rate of three revolutions per second and is released on the upward part of the circular motion when it is 1.5 m above the ground. the ball travels straight upward. in the absence of air resistance, to what maximum height above the ground does the ball rise?

What is the answer for this. the correct answer only

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
