Two spheres, a and b, are simultaneously projected horizontally from the top of a tower. sphere a has a horizontal speed of 40.0 meters per second and sphere b has a horizontal speed of 20.0 meters per second. which statement best describes the time required for the spheres to reach the ground and the horizontal distance they travel? [neglect friction and assume the ground is level.]
sphere a hits the ground before sphere b, and sphere a lands twice as far as sphere b from the base of the tower.
both spheres hit the ground at the same time and at the same distance from the base of the tower.
both spheres hit the ground at the same time, but sphere a lands twice as far as sphere b from the base of the tower.
