A large mass piece of 35 kg is attached to a rope and hangs from a beam. David pulls the mass piece at an angle of 35° to the horizontal with a force F of 500 N and keeps it
in this position for a while. Ignore the mass of the rope in all cases.

1)calculate vertical and horizontal components ?

2)calculate late horizontal and vertical T exerts on the mass when it is pulled at and angle F and still hangs?

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
