Two teams are engaging in a tug–of-war. The rope suddenly snaps. Which statement is true about the forces involved?  a. The forces exerted by the two teams are no longer equal; the teams will accelerate in opposite directions as a result.  b. The forces exerted by the players are no longer balanced by the force of tension in the rope; the teams will accelerate in opposite directions as a result.  c. The force of gravity balances the forces exerted by the players; the teams will fall as a result  d. The force of tension in the rope is transferred to the players; the teams will accelerate in opposite directions as a result.

Normal forces and frictional forces are always... A. parallel to surfaces B. Perpendicular to surfaces  C. Parallel and perpendicular to surfaces respectively D. Perpendicular and parallel to surfaces respectively

7. Using two ropes, Eric and Arya pull Josh on a skateboard. There is an angle of 35° between Eric and Arya. Eric pulls with a force of 300N and the resultant force is 500N. Determine the angle the resultant force makes with Eric's force. Include a detailed diagram. a. b. With what force is Arya pulling the skateboard?
