... 1. A tennis player hits a ball 2.0 m above the ground. The ball leaves his racquet with a speed of 20.0 m{s at an angle of 5˝ above the horizontal. The horizontal distance to the net is 7 m and the net is 1 m high. Does the ball clear the net? If so, by how much? If not, by how much does it miss? So ...

Torque - rcasao
... As we have seen over and over again, a force is a push or a pull, and an unbalanced force causes an object to move (to accelerate). All the motion we have dealt with so far has moved objects from one point in space to another. This type of motion involving a displacement is called translational moti ...
