What is the centripetal force required to cause a 4000 lb car to go around a curve of 900 ft radius and a speed of 600 miles per hour?

A horizontal force of 3,000,000 dynes can keep a 50 kg mass in uniform motion. What is the coefficient of the kinetic friction? At what angle must the plane be tilted to allow the mass to slide?

In the first equation, subtract 2y on both sides and you'll have 5x=7-2y. After that, divide both sides by 5, you get x=(7-2y)/5 In the second equation, substitute the value of x in the first equation to the x in the second equation, you get -2[(7-2y)/5]+...

vi = 15m/s a = 9.805m/s^2 t = 2s Substitute all these values and you'll have V

y=5-3x
