In 1978, geoff capes of the united kingdom won a competition for throwing 5 lb bricks; he threw one brick a distance of 44.0 m. suppose the brick left capes' hand at an angle of 45.0° with respect to the horizontal a. what was the initial speed of the brick? b. what was the maximum height reached by the brick?

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
