A 0.032 kg bullet strikes a 4.8 kg stationary piece of lumber and embeds itself in the wood. The piece of lumber and bullet fly off together at 7.2 m/s. What was the original speed of the bullet?

A hungry 5.37 kg fish swimming at 1.86 m/s swallows a 0.96 kg fish that was swimming towards it at 2.98 m/s. What is the final speed (in m/s) of the formerly hungry fish?

A baseball of mass m = 0.35 kg is dropped from a height h1 = 2.85 m. It bounces from the concrete below and returns to a final height of h2 = 1.39 m. Neglect air resistance.Randomized Variablesm = 0.35 kgh1 = 2.85 mh2 = 1.39 m a. What is this impulse, in kilogram meters per second?  b. If the baseball was in contact with the concrete for t = 0.01 s, what average force Fave did the concrete exert on the baseball, in newtons?

A 20 gg ball of clay traveling east at 2.0 m/sm/s collides with a 20 gg ball of clay traveling north at 2.0 m/sm/s.   What is the speed of the resulting 40 gg ball of clay? Express your answer with the appropriate units.

Two rocks collide in outer space. Before the collision, one rock had mass 15 kg and velocity m/s. The other rock had mass 10 kg and velocity m/s. A 1 kg chunk of the first rock breaks off and sticks to the second rock. After the collision the 14 kg rock has velocity m/s. After the collision, what is the velocity of the other rock, whose mass is now 11 kg? Additional Materials eBook m/s

An oxygen atom (mass 16 u) moving at 733 m/s at 15.0° with respect to the i ^ direction collides and sticks to an oxygen molecule (mass 32 u) moving at 528 m/s at 128° with respect to the i ^ direction. The two stick together to form ozone. What is the final velocity of the ozone molecule?

A woman with a mass of 59 kg runs at a speed of 6 m/s and jumps onto a giant 30 kg skateboard initially at rest. What is the combined speed of the woman and the skateboard?

Betty (mass 35 kg) stands on an ice rink as Bubbles (her hyperactive puppy, mass 8.6 kg)) runs towards her and leaps into her arms. If they move off together with a speed of 0.76 m/s, how fast (in m/s) was Bubbles moving when Betty caught her?

MO-6 The Meteor Crater in Arizona is about 1,200m wide and 200m deep. It is believed to have been formed 20,000 years ago when a meteor with a mass of 5.0x10"kg moving at 7.2km/s collided and merged with the earth. If the earth had been at rest prior to the collision, what would the speed of the earth have been after this collision? The mass of the earth is 5.98x10"kg. 24

A 3.25 µg particle moves at 2.09 × 10° m/s. What is its momentum p? p = kg-m/s
