A soccer ball having a mass of 0.43 kg enters the goal with a momentum of 5.16 kg-m/s after it was kicked over a distance of 18 meters. How much time did it take for the ball to reach the goal?

A spaceship of mass 2.30x10 kg is cruising at a speed of 4.60x105 m/s when the antimatter reactor fails, blowing the ship into three pieces. One section, having a mass of 5.20x105 kg, is blown straight backward with a speed of 2.50x106 m/s. A second piece, with mass 7.70x105 kg, continues forward at 1.00x106 m/s.

A 44 kg school kid is hurrying to catch the school bus. He runs at 3.1 m/s. How many N.s of momentum does he have?

(a)A bullet with a mass of 2.00 g moves at a speed of 1.50 ✕ 103 m/s. If a baseball of mass 142 g has the same momentum as the bullet, what is its speed (in m/s)?  m/s (b)Which has greater kinetic energy, the ball or the bullet? The bullet has greater kinetic energy.The ball has greater kinetic energy.    Both have the same kinetic energy

I.  A lump of clay (m = 3.01 kg) is thrown towards a wall at speed v = 3.15 m/s.  The lump sticks to the wall.  (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   II.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.15 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   III.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.24 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic…

A small truck of mass 600 kg moves with a velocity of 60 m / s. If an object of mass 1200 kg has the same momentum as the truck, then its velocity should be (Instructions: Please do not write the units in your answer. Write only the number.)

in 8.43s, 168 bullets strike and embed themselves in a wall. The bullets strike the wall perpendicularly. Each bullet has a mass of 5 x 10-3 kg and a speed of 931 m/s. (a) What is the average change in momentum per second for the bullets? (b) Determine the average force exerted on the wall. (c) Assuming the bullets are spread out over an area of 2.76x 10-4 m7 obtain the average pressure they exert on this region of the wall.

The Serengeti region of central Africa is home to a myriad of animal species, including the impala, Thomson’sgazelle, and the fastest land animal, the cheetah. On one particular day, a 64-kg impala is running at45 km/h due north, and a 25-kg Thomson’s gazelle is running at 77 km/h due east. If a chasing cheetah witha mass of 70 kg has twice the momentum as the impala and gazelle combined, fnd the direction andmagnitude of the cheetah’s velocity.

Physics: Unit: Momentum and collisions Consider a collision in one dimensional that involves two objects of masses 4.5 kg and 6.2 kg. The larger mass is initially at rest, and the smaller mass has an initial velocity of 16 m/s (E). The final velocity of the larger object is 10.0 m/s (E). Calculate the final velocity of the smaller object after the collision.(Hint: = m1Vi1 + m2Vi2 = m1Vf1 + m2Vf2)

An object at rest explodes and breaks into two pieces that move away. Which statement can never be correct?     Both pieces have the same speed.     Both pieces have the same momentum.     Both pieces have the same mass.
