Answer:
2m/s²
Explanation:
Given parameters:
Net force on the car = 2000N
Acceleration = 4m/s²
Unknown:
Acceleration of a car twice the mass = ?
Solution:
Let us first find the mass of the car;
Force = mass x acceleration
Mass =
Mass = = 500kg
Now,
whose mass is twice that of the car
Mass of the new car = 2 x 500 = 1000kg
So;
Acceleration =
Acceleration = = 2m/s²
