18. A mass, M, suddenly fissions into two pieces which fly apart to a constant separation...
A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another, one in the x direction another in the y direction. Both of these pieces fly away with a speed of V = 35 m/s. The third piece has three times the mass of the other two pieces. Part (a) Write an expression for the speed of the larger piece, that is in terms of only the variable V. Part (b) What is the numeric value for...
Two identical objects of mass m are a distance R apart and feel a gravitational force of attraction of F. If the distance increases to 5R, what will be the force between the two objects? Select one: a. F/5 b. F/25 c. F d. 25F e. 5F
Two equal-mass stars maintain a constant distance apart of 1.7×1011 m and rotate about a point midway between them at a rate of one revolution every 21.6 yr . A) Why don't the two stars crash into one another due to the gravitational force between them? B) What must be the mass of each star? (Express your answer using two significant figures.)
Two equal-mass stars maintain a constant distance apart of 1.1×1011 m and rotate about a point midway between them at a rate of one revolution every 16.6 yr . PART A: Why don't the two stars crash into one another due to the gravitational force between them? PART B:What must be the mass of each star?
Problem 1 An object of mass m1 travels through empty space at a constant speed until it strikes and sticks to a second object. As observed from the frame where the second object is motionless, the first object was traveling at a speed of vi. In that same frame, both objects travel at a speed of v after the collision. a. What is the general expression for the mass of the second object in terms of mi, vi, and v?...

1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...
An object of mass m is connected to a light spring with a force constant of kH N/meter which oscillates on a frictionless horizontal surface with Simple Harmonic Motion. At t = 0 the spring was at rest but is compressed x = A meter maximum during oscillation. Write the equation of motion from Newton's 2nd law FH = m·a and Hook's Law FH = -kH·x. Because of the starting position assume a solution is x = A sin(ωt) a...
6. Consider a horizontal spring with spring constant k. A block with mass m is pushed far to the left against the spring until the spring is compressed a distance r relative to its relaxed length. A second block, which is stationary and also has a mass m, is located to the right of the spring im rrm a) We release the first block from rest. Due to the force from the spring, it slides to the right and eventually...
