Answer:
Force = 175000 newtons
Final momentum = 1050000 N*S
Explanation:
We know that force is equal to Mass * acceleration
We also know that the mass of object is 15,000kg.
We know acceleration is (change in velocity)/time
Our initial velocity is 180m/s
our final velocity is 250 m/s
the time it took was 6 seconds
our change in velocity is 250 - 180 = 70
the time it took was 6 seconds
a = 70/6 = 11.67 m/s^2
So we can calculate force, by doing Mass * Acceleration, which is 15,000 * 11.67
Force is 175000 Newton's
Momentum is calculated by Velocity * mass or Force * time
we could do either one
<u>velocity</u><u> </u><u>*</u><u> </u><u>mass </u>way
we are given final velocity is 250 m/s, and that the initial velocity is 180 m/s. We first have to find the change in velocity by subtracting final and initial and get 70, and then we multiply that by the mass, which is 15000 kg.
we multiply them together and get 1050000 Kg*m/s
<u>Force </u><u>*</u><u> </u><u>time </u>way
We just calculated the force above, and got 175050 newton's. from that we just multiply by the time, which is 6 seconds
and we get a result of
1050000 Newton*seconds
*** remember newton*seconds is the same as kg*m/s
