(a) The momentum of a moving object is given by:
where m is the mass of the object and v is its speed. In this problem, the mass of the elephant is and its speed is , therefore its momentum is
(b) We can use the same formula to calculate the momentum of the tranquilizer dart, whose mass is and whose speed is :
we see that the elephant's momentum is much larger than the momentum of the dart.
(c) Again, using the same formula, the mass of the hunter is , his speed is , therefore his momentum is
Answer: that's where the fuel pump comes in handy. The fuel pump pumps the gas out and brings it throught the fuel lines to the engine. With the fuel pump you would have to have the line to the engine on the bottom.

Answer:
Explanation:
average speed is distance traveled over time
v = (50 + 30(1.5)) / (2 + 1.5) = 27.1428571...
v = 27 km/hr
Answer:
Mass of the rocket, m = 20,000 kg Initial acceleration, a = 5 m/s Acceleration due to gravity, g = 10 m/s Using Newton’s second law of motion, the net force (thrust) acting on the rocket is given by the relation: F – mg = ma F = m ( g + a ) = 20000 × (10 + 5)
Explanation:
Answer:
Temperature is an indirect measurement of the heat energy in a substance.
