What is the magnitude of the scooter’s acceleration?

A net force of 6.8 N accelerates a 31 kg scooter across a level parking lot. What is the magnitude of the scooter’s acceleration?
A. 0.22 m/s²
B. 0.69 m/s²
C. 3.2 m/s²
D. 4.6 m/s²

Additionally, an airplane with a mass of 12,000 kg tows a glider with a mass of 6,000 kg. If the airplane's propellers provide a net forward thrust of 36,000 N, what is the acceleration of the glider? (Please disregard friction.)
A. 2.00 m/s²
B. 3.00 m/s²
C. 6.00 m/s²
D. 9.80 m/s²

Both of these are found using F=m*a, where F is the net force, m is the total mass and a is the acceleration.

Scooter

A .22 m/s^2

6.8/31=a

Plane and glider

A. 2.00 m/s^2

3.6/(1.2+0.60)

2.0 m/s^2
