Answer:
The magnitude of the net force that produces the deceleration = 1744 N
Explanation:
Using the equations of motion, we can find the deceleration of the car and thereby find the magnitude of the met force that produces such deceleration
v = u + at
where v = final velocity = 18.8 m/s
u = initial velocity = 29.5 m/s
t = 9.14 s
a = ?
v = u + at
18.8 = 29.5 + 9.14a
9.14a = 18.8 - 29.5 = -10.7
a = - 1.171 m/s²
Magnitude of Force causing deceleration = ma = 1490 × 1.171 = 1744 N
