Answer:
240N
Explanation:
The formula for force is F=mass×acceleration.
Therefore, Force= 120×2= 240N
Answers
The car's forward motion is opposed by the friction between the road and the tires and by the resistance of the air.
Velocity
E = P.E + K.E
P.E = mgh
K.E = ½ mv²
200 N = 200 Newtons
Just use the formula F = m*a
F = Force in Newtons
m = mass and is 20 kg
a = acceleration and is 10 m/s^2
F = 20 * 10
F = 200 Newtons.
