What forces act on you as you walk across a room? Draw a free-body diagram showing all of them. Which force or forces propel you forward? Why is it more difficult to walk on a slippery surface than on a nonslippery one? Explain how you use Newtons third law to control your motion.
The wheels of a midsize car exert a force of 2100 N backward on the road to accelerate the car in the forward direction. If the force of friction including air resistance is 250 N and the acceleration of the car is 1.80 m/s2, what is the mass of the car plus its occupants? Explicitly show how you follow the steps in the Problem-Solving Strategy for Newton's laws of motion. For this situation, draw a free-body diagram and write the net force equation.
A runner pushes against the track, as shown. (a) Provide a free-body diagram showing all the forces on the runner. (Hint: Place all forces at the center of his body, and include his weight.) (b) Give a revised diagram showing the xy -component form. (credit: modification of work by “Greenwich Photography”/Flicke)
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.
Consider the 65.0-kg ice skater being pushed by two others shown below. (a) Find the direction and magnitude of Ftot . the total force exerted on her by the others, given that the magnitudes F1and F2are 26.4 N and 18.6 N, respectively. (b) What is her initial acceleration if she is initially stationary and wearing steel-bladed skates that point in the direction of Ftot ? (c) What is her acceleration assuming she is already moving in the direction of Ftot ? (Remember that friction always acts in the direction opposite that of motion or attempted motion between surfaces in contact)
The traffic light hangs from the cables as shown. Draw a free-body diagram on a coordinate plane for this situation.
Drawing Free-Body Diagrams In completing the solution for a problem involving forces, what do we do after constructing the tree-body diagram? That is, what do we apply?
Suppose Kevin, a 60.0-kg gymnast, climbs a rope. (a) What Is the tension in the rope if he climbs at a constant speed? (b) What is the tension in the rope if he accelerates upward at a rate of 1.50m/s2 ?
A block of mass 3m is placed on a frictionless horizontal surface, and a second block of mass m is placed on top of the first block. The surfaces of the blocks are rough. A constant force of magnitude F is applied to the first block as in Figure P4.68. (a) Construct free-body diagrams for each block. (b) Identify the horizontal force that causes the block of mass m to accelerate. (c) Assume that the upper block does not slip on the lower block, and find the acceleration of each block in terms of m and F. Figure P4.68
The force on a baseball as with a bat can be more than 8,000 lb. No human can push on a bat with that much force. What is happening in this instance?
During the Olympics Speed Skating event, two skaters on the same team are skating [F] one in front of the other. While gliding, the skater behind pushes the skater in front. What would happen to each skater's motion? Give a FBD of each skater and explain using one of Newton's Law's (be sure to give which law best describes this)
Three blocks A, B, and C stand next to each other as shown in the figure. A force F is applied to push block C directly and sends the blocks accelerating to the right with acceleration of 10 m/s2. Let's assume there is no friction between the blocks and the ground. The mass of A, B, and C are 12.300, 89.200, and 154.100 kg, respectively. What is the force applied on block C by block B (in unit of N)?
