Only very small cars are that light, Lotus elise is 725kg, current Fiat 500 (865-980kg)
smart car 730kg, early Ford Fiesta.
The car with a mass of 1500 kg has more inertia than the car with a mass of 900 kg. Inertia is directly proportional to mass, so the car with greater mass will have greater inertia.
When moving the 1500kg has more inertia.
When moving the 1500kg has more inertia.
The force required to accelerate the car can be calculated using Newton's second law, which states that force equals mass times acceleration. So, the force needed to accelerate a 900-kg car at a rate of 3 m/s^2 would be 900 kg * 3 m/s^2 = 2700 N.
5,400 N.
Using the formula F = ma, a 900 kg car would require 5400 Newtons to achieve an acceleration of 6 meters per second per second.(1 newton = 1 kg-m/sec2 )
Momentum = m V = (900) (27) (1609.344 m/mi) = 3,910,706 kg-m/sec (rounded)
The kinetic energy of the 12000-kg train would be much greater than that of the 900-kg compact car, as kinetic energy is directly proportional to the mass of the object. Therefore, the train would have significantly more kinetic energy than the compact car when traveling at the same speed.
5,400 N.
B. 5,400 N
-530 (m+9) = 10.0
1980lbs. (2.2lbs per kg)... (900*2.2=1980)
