Kramer goes bowling and decides to employ the force of gravity to "pick up a spare." He rolls the 6.50 kg bowling ball very slowly so that it comes to rest a center-to-center distance of 0.245 m from the one remaining 2.00 kg bowling pin. Treat both the ball and the pin as point objects, and determine the magnitude of the force of gravity ?⃗ grav between them.

b) A 20.0kg crate is at rest on a floor as shown. The coefficient of static friction between the crate and floor is 0.625 and the coefficient of kinetic friction is 0.525. Calculate the minimum horizontal force (F) required to make the crate start sliding. F The minimum horizontal force (F) required to make the crate slide is =

A 92-kg astronaut and a 1200-kg satellite are at rest relative tothe space shuttle. The astronaut pushes on the satellite, giving it aspeed of 0.14 m/s directly away from the shuttle. Seven and a halfseconds later the astronaut comes into contact with the shuttle.What was the initial distance from the shuttle to the astronaut? Explain and labled the problem.

Do Two skydivers are holding on to each other while falling straight down at a common terminal speed of 61.90 m/s. Suddenly, they push away from each other. Immediately after separation, the first skydiver, who has a mass m₁ of 94.80 kg, has a velocity U₁ with the following components ("straight down" corresponds to the positive z-axis). U1, y = 4.750 m/s U1,2 = 61.90 m/s What are the x- and y-components of the velocity v₂ of the second skydiver, whose mass m₂ is 57.70 kg, immediately after separation? Assume that there are no horizontal forces of air resistance acting on the skydivers.

Two blocks, which can be modeled as point masses, are very much connected by a massless string which passes through a hole in a frictionless table. A tube extends out of the hole in the table so that the portion of the string between the hole and M1 remains parallel to the top of the table... With that being said, The blocks have masses M1 = 1.2 kg and M2 = 2.7 kg. Block 1 is a distance r = 0.55 m from the center of the frictionless surface. Block 2 hangs vertically underneath. 1) Assume that block two, M2, does not move relative to the table and that block one, M1, is rotating around the table. What is the speed of block one, M1, in meters per second?  2) How much time, in seconds, does it take for block one, M1, to make one revolution?

A horizontal force with magnitude of 52.0N on a box and produces acceleration with magnitude 3.60 m/s^2. What is the mass of the box?

In the figure shown below, two masses with mass ?1 = 14.0??, ?2 = 17.0 ?? are hanging stationary from the ceiling.

An 77.0 kg spacewalking astronaut pushes off a 650 kg satellite, exerting a 105 NN force for the 0.430 ss it takes him to straighten his arms. How far apart are the astronaut and the satellite 1.40 min after the push begins?

An 85.0 kg spacewalking astronaut pushes off a 640 kg satellite, exerting a 120 N force for the 0.600 s it takes him to straighten his arms. How far apart are the astronaut and the satellite after 1.00 min?
