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.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
