Answer:
50kg
Explanation:
mass = force/acceleration
50kg = 350/7
The ammeter reading (current) will decrease.
V=IR
I = V/R
so I is inversely proportional to R, i.e. increasing R will cause I to decrease
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 :)
Try looking it up. that might help
They both have a constant acceleration of g (9.8 m/s) So they both have equal accelerations. This is according to the law of gravity
