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?
An SUV is traveling at a speed of 18 m/s. If the SUV has a mass of 1,550 kg, -3487.5 N of force must be applied to stop it in 8 seconds. Solution: Given: V1 = 18 m/s; Vo = 0 m/s; t=8; (0-18m/s)/8 = -2.25m/s^2 Then we compute for the Force. [ F=ma; F=1550*-2.25m/s^2; F= -3487.5 N. ]

11. An SUV is traveling at a speed of 18 mIs. If the SUV has a mass of 1,550 kg, what force must be applied to stop it in 8 seconds? O A. —3,487.5 N O B. —4,030.7 N O C.—2.25N O D. —2,7000 N
An SUV is traveling at a speed of 18 mIs. [ If the SUV has a mass of 1,550 kg, —3,487.5 N must be applied to stop it in 8 seconds. Solution: Vi = 18 m/s , Vf = 0 m.s , m = 1,550 kg , t = 8 sec By equation of motion , we get Vf = Vi + at 0 = 18 + a(8) -18 = 8a 8 a = =18 a = -18/8 A = - 9/4 Now F = ma F = (1550)( - 9/4) F = - 3,487.5 N ]
