If set into motion find the frequency of the spring with a 1

If set into motion, find the frequency of the spring with a 10 N weight. 1.80 Hz 0.75 Hz 93 1 Hz 2.36 Hz If set into motion, find the period of the spring with a 10 N weight. 0 42 s 1.33 s 0.01 s 0.56 s A tow truck exerts a force of 450 Ib_f on a car, causing it to accelerate at 10 ft/s^2. What is the mass of the car?45 slugs 45 lbm 45 kg None of the above

Solution

F = 450 lb_f =2001.7 N

a = 10 ft/sec² = 3.048 m/sec ²

^{newton\'s first law-}

F = m*a

m=F/a = 450/10 = 45 slungs

m=F/a=2001.7/3.048=656.726 Kg

1 slungs=14.594 Kg
