A bullet of mass m = 8.00 g is fired into a block of mass M = 220 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.60 m from the bottom of the table. Determine the initial speed of the bullet. __ m/s

Please help me understand the concept of this practice problem and how to work these types out. Thanks

A rubber ball with a mass of 0.115 kg is dropped from rest. From what height (in m) was the ball dropped, if the magnitude of the ball's momentum is 0.780 kg m/s just before it lands on the ground? m

m2 m h=7.0m ☐ Figure 1: Diagram for Problem 15 15) During a test investigation, a 40-gram bullet is fired towards a stationary block of 1.0-kg mass causing a perfectly in-elastic collision. After the collision, the block-bullet system slides up a smooth ramp, eventually coming to rest at an elevation of 7.0 meters. Calculate the speed of the bullet. Must show all steps including the equations being used.

Please solve with detailed explanation. Thank you

Question Vị = 8 m/s A Vi = 16 m/s Objects A and B (Mass A = 6kg, Mass B = 4kg) have a head-on collision as shown. Immediately before the collision, Object A has a velocity of 8 m/s to the right, and Object B has a velocity 16 m/s to the left. Immediately after the collision, Object A has a velocity 4 m/s to the left. What is the magnitude and direction of the velocity of Object B ilmmediately after the collision? %3D Answer

A bullet of mass m = 8.00 g is fired into a block of mass M = 240 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.80 m from the bottom of the table. Determine the initial speed of the bullet. m/s

A 0.250 kg toy car moving with a speed of 0.820 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision? Force (N) 40- 0 0.01 Time (s) 0.02 final speed = 0.684 Attempt 4 Incorrect m/s

A bowling ball of mass Mb= 4.1 kg is rolled down the lane with the velocity of V1=2.1 m/s it’s strikes a single remaining pain of a mass Mp= 0.96 kg head on. After the collision the bowling ball has a velocity (in the same direction) of V2 = 1.75 m/s Part A. Write an expression for the velocity of the pin in the horizontal direction after the impact, Vp. Part B. What is the pin speed in m/s ? Part C. Assuming the coefficient of friction is UK = 0.1 how far in meters cut the pin slide before stopping if it doesn’t topple ?

Batman (mass = 86.5 kg) jumps straight down from a bridge into a boat (mass = 493 kg) in which a criminal is fleeing. The velocity of the boat is initially +13.3 m/s. What is the velocity of the boat after Batman lands in it? Number i Units
