A powerful motorcycle can produce an acceleration of 3.50m/s2 while traveling at 90.0 km/h. At that speed, the forces resisting motion, including friction and air resistance, total 400.0 N. (Air resistance is analogous to air fiction. It always opposes the motion of an object.) What is the magnitude of the force that motorcycle exerts backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 245 kg?

(a) Find the component form of the net force. (b) Find the magnitude of the resultant (net) force on the tree and the angle it makes with David’s rope.
At a circus, a donkey pulls on a sled carrying a small clown with a force given by . A horse pulls on the same sled, aiding the hapless donkey, with a force of The mass of the sled is 575 kg. Using and from for the answer to each problem, find (a) the net force on the sled when the two animals act together, (b) the acceleration of the sled, and (c) the velocity after 6.50 s.
What force does a trampoline have to apply to Jennifer, a 45.0-kg gymnast, to accelerate her straight up at 7.50m/s2 ? The answer is independent of the velocity of the gymnast—she can be moving up or down or can be instantly stationary.
A history book is lying on top of a physics book on a desk, as shown below a free-body diagram is also shown. The history and physics books weigh 14 N and 18 N, respectively. Identify each force on each book with a double subscript notation (for instance, the contact force of the history book pressing against physics book can be described as F HP), and determine the value of each of these forces, explaining the process used.
