<h3><u>Answer;</u></h3>
M.A = 4.25
<h3><u>Explanation;</u></h3>
Mechanical advantage is the ratio of the force required to do something in comparison to the actual force required using a simple machine.
It is the ratio of output force to the input force.
M.A = Output Force/ Input Force
Out put force 85 Kg = 850 N
Input force = 200 N
Therefore;
M.A = 850 N/200 N
= 4.25
The answer is Zip.
(This is just extra text so brainly lets me comment the answer)
1) The acceleration
Acceleration = Change in Speed / Time
Acceleration = (12 - 2) / 2
Acceleration = 10 / 2
Acceleration = 5m/s^2 (This is the unit for acceleration)
2) Initial momentum
Momentum = Mass x Velocity
Momentum = 1500 x 2
Momentum = 3000kg m/s (This is the unit for momentum)
3) Final momentum
Momentum = Mass x Velocity
Momentum = 1500 x 12
Momentum = 18000kg m/s
4) Change in momentum
Change in momentum = Final momentum - Initial momentum
Change in momentum = 18000 - 3000
Change in momentum = 15000kg m/s
5) Force
Force = Mass x Acceleration
Force = 1500 x 5
Force = 7500N (This is the unit for force)
Hope that helps :)
In my school we have recycle bins than store trash, plastic, and paper. Every Friday a group of students in with the responsibilities collect them all together around the school and yeah...
