The formula for acceleration, or average acceleration, is a=(vf-vi) divided by (tf-ti) .
a= Acceleration (or average acceleration
vf= Final Velocity
vi= Initial Velocity
tf= Final Time
ti= Initial Time
hope i helped you out!
Newton's law of universal gravitation gives the gravitational force between two objects:
F = GMm/r²
F = gravitational force, G = gravitational constant, M & m are the masses of the two objects, r = distance between the objects
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 :)
