Answer:
this is just a guess bc i only looked at it for 5 seconds but i think 150 m/s
Answer:
Quick maths
First you find the fafarick and the lalickc and the caprisum and the joinnt
2500
--------=3125
0.8
This can be can be viewed as compression due to the direction of the arrows.
The car is accelerating at 3 m/s² in the positive direction (to the right). By Newton's second law, the net force on the car in this direction is
∑ F = F[a] - F[f] - F[air] = ma
3100 N - 200 N - F[air] = (650 kg) (3 m/s²)
Solve for F[air] :
F[air] = 3100 N - 200 N - (650 kg) (3 m/s²)
F[air] = 3100 N - 200 N - 1950 N
F[air] = 950 N
