An SUV is traveling at a speed of $18 m / s$. If the SUV has a mass of $1,550 kg$, what force must be applied to stop it in 8 seconds?
A. -2.25 N
B. $-2,700.0 N$
C. $-3,487.5 N$
D. $-4,030.7 N$
Answer (2)
The force required to stop the SUV is calculated using Newton's second law. The acceleration needed to stop the vehicle in 8 seconds is − 2.25 m / s 2 , leading to a total force of − 3487.5 N . Thus, the correct answer is C. -3487.5 N.
