-A model airplane with a mass of 0.211kg pulls out a dive. The bottom of the dive is a circular arc with a radius of 25.6m. At the bottom of the arc, the plane's speed is a constant 21.7m/s. Determine the magnitude of the upward lift on the plane's wings at the bottom of the arc.

-A curved road with a radius of 450m in the horizontal is banked so that the cars can safely navigate the curve. Calculate the banking angle for the road that will allow a car travelling 97km/h to make it safely around the curve when the road is covered with black ice(assume no friction).

-A 2.ookg mass is spinning horizontally in a circle on a virtually frictionless surface. It completes 5.00 revolution in 2.00s. The mass is attached to a string 4.00m long. Calculate the magnitude of the tension in the string. Air resistance is negligible.

-A car with a mass of 1000kg is travelling over the top of a hill. The hill's curvature has a radius of 40m, and the car is travelling at 15m/s.

a) draw a diagram b) determine the magnitude of the normal force c) determine the speed required to make the driver feel weightless at the top of the hill.

-A car moves in a horizontal circle on a test track with a radius of 1.2*10^2 meters. The coefficient of static friction between the tires and the road is 0.72. Draw a diagram, and calculate the maximum speed of the car.

-An air puck with a mass of 0.26kg is tied to a string and moves at a constant speed in a circle of radius 1.2metres. The other end of the string goes through a hole in the air table and straight down to a suspend mass of 0.68kg, which hangs at rest. Calculate the speed of the air puck.
