6. Two spheres, A and B, are simultaneously projected horizontally from the top of a tower. Sphere A has a horizontal speed of 40. meters per second and sphere B has a horizontal speed of 20. 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.] A) Both spheres hit the ground at the same time and at the same distance from the base of the tower. B) 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. C) Both spheres hit the ground at the same time, but sphere B lands twice as far as sphere A from the base of the tower. D) Sphere A hits the ground before sphere B, and sphere A lands twice as far as sphere B from the base of the tower 7. Equilibrium exists in a system where three forces are acting concurrently on an object. If the system includes a 5.0-newton force due north and a 2.0-newton force due south, the third force must be A) 7.0 N south C) 3.0 N south B) 7.0 N north D) 3.0 N north

6. Two spheres, A and B, are simultaneously projected
horizontally from the top of a tower. Sphere A has a
horizontal speed of 40. meters per second and sphere
B has a horizontal speed of 20. 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.]
A) Both spheres hit the ground at the same time and
at the same distance from the base of the tower.
B) 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.
C) Both spheres hit the ground at the same time, but
sphere B lands twice as far as sphere A from the
base of the tower.
D) Sphere A hits the ground before sphere B, and
sphere A lands twice as far as sphere B from the
base of the tower
7. Equilibrium exists in a system where three forces are
acting concurrently on an object. If the system
includes a 5.0-newton force due north and a
2.0-newton force due south, the third force must be
A) 7.0 N south
C) 3.0 N south
B) 7.0 N north
D) 3.0 N north
