As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 21.5 m/s. In the process, he moves his hand through a distance of 1.45 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.

When a 1.50-kg dress hangs midway from a taut clothesline stretched between two poles planted 7.50 m apart, the clothesline is seen to sag 0.0500 m. a. Draw a free-body diagram of the dress. b. What is the tension produced on the clothesline by the dress? Assume the clothesline is massless.
Suppose two children push horizontally, but in exactly opposite directions, on a third child in a wagon. The first child exerts a force of 75.0 N, the second exerts a force of 90.0 N, friction is 12.0 N, and the mass of the third child plus wagon is 23.0 kg. (a) What is the system of interest if the acceleration of the child in the wagon is to be calculated? (See the free-body diagram.) (b) Calculate the acceleration. (c) What would the acceleration be if friction were 15.0 N?

A body of mass m has initial velocity v0 in the positive x -direction. It is acted on by a constant force F for time t until the velocity becomes zero; the force continues to act on the body until its velocity becomes v0 in the same amount of time. Write an expression for the total distance the body travels in terms of the variables Indicated.
A car is moving forward slowly and is speeding up. A student claims that the car exerts a force on itself or that the cars engine exerts a force on the car. (a) Argue that this idea cannot be accurate and that friction exerted by the road is the propulsive force on the car. Make your evidence and reasoning as persuasive as possible. (b) Is it static or kinetic friction? Suggestions: Consider a road covered with light gravel. Consider a sharp print of the tire tread on an asphalt road, obtained by coating the tread with dust.
A baseball catcher is performing a stunt for a television commercial. He will catch a baseball (mass 145 g) dropped from a height of 60.0 m above his glove. His glove stops the ball in 0.0100 s. What is the force exerted by his glove on the ball?
Twenty people participate in a tug-of-war. The two teams of ten people are so evenly matched that neither team wins. After the game they notice that a car is stuck in the mud. They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?
Mechanic Physics: Please make sure this is right!! The only force acting on a 1.7 kg body as it moves along the positive x axis has an x component Fx = -4x N, where x is in meters. The velocity of the body at x = 2.6 m is 9.6 m/s. (a) What is the velocity of the body at x = 4.7 m? (b) At what positive value of x will the body have a velocity of 6.0 m/s?
Please Provide Handwritten Answer . A golf club impacts a golf ball with a force equal to 100* [(t+1)^4]*t (N) where t is in seconds. The golf ball lands 1000m away from the tee after the strike of the club on the 1kg ball at rest. If the ball is observed to launch at a 20 deg. angle after impact, what is the hang time of this golf ball?___sec Assume 10 m/s^2 for acceleration due to gravity.

Three blocks A, B, and C stand next to each other as shown in the figure. A force F with magnitude 157.0 N is applied to push block C directly and sends the blocks accelerating to the right. Let's assume there is no friction between the blocks and the ground. The mass of A, B, and C are 2.8, 29.5, and 84.8 kg, respectively. What is the force applied on block B by block A (in unit of N)?
