Calculate the momentum pelephant of a 2140 kg elephant charging a hunter at a speed of 7.63 m/s . pelephant= kg⋅m/s Compare the

elephant's momentum with the momentum pdart of a 0.0415 kg tranquilizer dart fired at a speed of 619 m/s . pelephant=pdart pelephant>pdart More information is needed to determine how the momentums compare. pelephant

Answer:

Momentum of elephant is greater than momentum of tranquilizer dart

Explanation:

m_e = Mass of elephant = 2140 kg

m_d = Mass of tranquilizer dart = 0.0415 kg

v_e = Velocity of elephant = 7.63 m/s

v_e = Velocity of tranquilizer dart = 619 m/s

Momentum of elephant

p_e=m_ev_e\\\Rightarrow p_e=2140\times 7.63\\\Rightarrow p_e=16328.2\ N.s

Momentum of tranquilizer dart

p_d=m_dv_d\\\Rightarrow p_d=0.0415\times 619\\\Rightarrow p_d=25.6885\ N.s

So, p_e>p_d

Momentum of elephant is greater than momentum of tranquilizer dart

Three boys of equal strength try to break a rope (and fail) by tying one end to a fence post and tugging on the other end. Three
podryga [215]

The best choice would be C. Keep one end of the rope tied to the post and have all six boys tug on the other end.

Reason:

A is not correct since in the first case which is B, untying the rope from the post and have 3 boys on each end of it tug, will provide equal or a near equal amount of tension since the boys are all within the same strength, however there can be variables that will affect the tension.

That means B would be true according to A, and then for C, having all six boys pull on the other end of the rope would provide greater tension, since if 3 boys of the same strength range can't break the rope when its tied to the fence, we add the other 3 boys of the same strength.

However, if 3 boys are on each end of the rope and of the same strength then the rope will not break since there is an equal amount of net force exerted on the rope.

We know that the fence can withstand the strength of 3 boys but if we add the other 3 boys then it could provide us with a different outcome.

3B < F

3B(2) ≥ F

So, therefore, our best choice would be C since A and B is incorrect.
