Question

You are designing a swing that will hang from a very large tree limb, and will pass out over the river, wing is 6. 20 meters long, and the maximum speed at the bottom is 15. 0 m/s, what is the tension in each of the two ropes of the swing at this point (if the person on the swing has a mass of 75 kg)? A 870-kg car is going around a banked (or angled) curve. This curve is angled at 28. 0degree from the horizontal, and the radius of the curve is 82. 0 m. The coefficient of static friction between the tires and the road is 0. 650. What is the maximum speed the car can have and still not slide off the road?

Explanation / Answer

Part 4 )

mv^2/L = T-mg

T = m[v^2/L + g ]

T = 3.456 x 10^3 N

Part 5 )

v = sqrt(mu*r*g*tantheta)

v = 16.67 m/s
