What is the velocity (in m/s) of a 915 kg car initially moving at 28.0 m/s, just after it hits a 145 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.) m/s

What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 135 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)

Consider a 935 kg car initially moving at 30.5 m/s.  a) what is the velocity of the car, in meters per second, just after it hits a 140-kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car.

What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 125 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)

A 1500 kg car is rolling horizontally at 2 m/s. You would like to stop the car by shooting a 10 kg blob of sticky clay at it, also horizontally. About how fast should you shoot the clay? O 25 m/s O2 m/s O 150 m/s 300 m/s O 0.01 m/s

A small comet moves at velocity 5050 m/s. Heat from the sun makes it break into two smaller pieces. The first piece has mass 1250-kg and velocity 5720 m/s in the same direction as before. The second piece has mass 2400-kg. What is its velocity? magnitude   direction

An object, in initially travelling 45° south of east at 100 m/s, explodes into three separate pieces. A 2.0 kg fragment travels due south at 105 m/s, while a 4.0 kg fragment travels due east at 155 m/s. The last fragment has a mass of 3.0 kg. The third fragment travels at an unknown velocity. Calculate its direction and magnitude of this unknown velocity.

A 38.0-kg boy, riding a 1.90-kg skateboard at a velocity of 5.60 m/s across a level sidewalk, jumps forward to leap over a wall. Just after leaving contact with the board, the boy's velocity relative to the sidewalk is 6.00 m/s, 9.60° above the horizontal. Ignore any friction between the skateboard and the sidewalk. What is the skateboard's velocity relative to the sidewalk at this instant? Be sure to include the correct algebraic sign with your answer.

2 trucks are driving an icy road and coming towards a 4way perpendicular intersection and driver A is driving a 3100 kg truck north-ward at 22m/s while driver B goes eastward in a 1100kg truck, they crash and stick together travelin at 59◦ north of East. What is Car B's original speed?

A rock (rock 1) is flying in the sky towards another rock, rock 2. Rock 1 has a mass of 60 kg, and Rock 2 has a mass of 10 kg. Rock 1 is in the sky with a speed of 25 m/s towards Rock 2, and rock 2 is movingtowards Rock 1 in the opposite direction with a speed of 35 m/s. If the two rocks stick together, what is their final velocity? Ignore air resistance and gravity. Is there a change in the kinetic energy of the system? If so, what is it?
