Calculate the momentum of a 2000-kg elephant charging a hunter at a speed of 7.50 m/s . (b) compare the elephant's momentum with
Sergio [31]

(a) The momentum of a moving object is given by:

p=mv

where m is the mass of the object and v is its speed. In this problem, the mass of the elephant is m=2000 kg and its speed is v=7.50 m/s, therefore its momentum is

p=(2000 kg)(7.50 m/s)=15000 kg m/s


(b) We can use the same formula to calculate the momentum of the tranquilizer dart, whose mass is m=0.04 kg and whose speed is v=600 m/s:

p=mv=(0.04 kg)(600 m/s)=24 kg m/s

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 m=90 kg, his speed is v=7.40 m/s, therefore his momentum is

p=mv=(90 kg)(7.40 m/s)=666 kg m/s

If a 50 kg box was accelerated to 10 m/s2, how much force was used?
Maru [420]

Answer:

<h2>500 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

mass in kg

acceleration in m/s²

From the question

force = 50 × 10 = 500

We have the final answer as

<h3>500 N</h3>

Hope this helps you
