World-class sprinters can accelerate out of the starting blocks with an acceleration that is nearly horizontal and has magnitude 15m/s^2.
How much horizontal force F must a sprinter of mass 55 kg exert on the starting blocks to produce this acceleration?
Which body exerts the force that propels the sprinter, the blocks or the sprinter?

10: A powerful motorcycle can produce an acceleration of while traveling at 90.0 km/h. At that speed the forces resisting motion, including friction and air resistance, total 400 N. (Air resistance is analogous to air friction. It always opposes the motion of an object.) What is the magnitude of the force the motorcycle exerts backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 245 kg? The powerful motorcycle, a chopper, in Problem...

Problem 3 (20 points) In the following figure, a horizontal force F is applied to a large block of mass M with a massless pulley attached to it. While the block M is moving to the right, the other two blocks mi and m2 remain stationary problem relative to M. All surfaces are frictionless for this (a) Draw separate free body diagrams for M(including the massless pulley), mi, and m2 respectively. On the free body diagrams, please only draw and...
3. (III) Three blocks on a frictionless horizontal surface are in contact with each other as shown in Fig. 4-54. A force F is applied to block A (mass mA). (a) Draw a free-body dia- gram for each block. Determine (b) the acceleration of the system (in terms of mA, mB, and mc), (c) the net force on each block, and (d) the force of contact that each block exerts on its neighbor. (e) If mA mB mc- F 96.0N,...

2. Two blocks of mass mį and m2 are stacked as shown on a frictionless surface. There is friction between the blocks with static friction coefficient us. A horizontal external force F is applied to the top block. o é Draw separate free-body diagrams for both masses according to the standards presented in class. Find an expression for the maximum force F that can be applied and yet the two blocks still move together. (Hint: both...
1. A Ferris wheel has a radius of 6 m and makes one revolution in 4seconds (i.e. onerevolution in approximately 12.6 seconds). A person with a mass of 50 kg is sitting on one of thebenches attached to the rim. What is the normal force acting on a the person at the highest pointof the rotating Ferris wheel? Approximate the acceleration due to gravity as 10 m/s2; on a Ferriswheel, the passengers are never upside down. 2. Consider what happens...
(10%) Problem 8: Two blocks connected by a string are pulled across a horizontal surface by a force applied to one of the blocks, as shown to the right. The mass of the left block m1 = 1.3 kg and the mass of the right block m2 = 3.1 kg. The angle between the string and the horizontal is = 61° The coefficient of kinetic friction between the blocks and the surface is u= 0.22. Each block has an acceleration...
