7. Snoopy is flying his vintage war plane in a "loop the loop" path chasing the Red Baron. Hisinstruments tell him the plane is level (at the bottom of the loop) and travelling with a speed of180 km/h. He is sitting on a set of bathroom scales, and notes that they read four times the normalforce of gravity on him. What is the radius of the loop? Answer in metres.

Given velocity v = 180 km/h weight read by the scale W' = 4W

You are an astronaut exploring an unknown planet, with a mass of 4.02×1024 kg, and a radius of 4,148 km. Draw a free body diagram of the forces acting as you stand on the surface. What is the magnitude of the acceleration due to gravity at the surface of the planet in m/s2? Calculate your answer to 2 sf.
A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 21.5 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 167 m), the block swings toward the outside of the curve. Then the string makes an angle with the vertical. Find 0.

A space probe is launched from Earth headed for deep space. At a distance of 10,000 km from Earth's center, the gravitational force on it is 900 N. What is the magnitude of the force when the probe is 30,000 km from Earth's center?
The passengers in a roller coaster feel 42 % heavier than their true weight as the car goes through a loop with a 30 m radius of curvature. What is the car's speed at the bottom of the loop? Use g = 10 N/kg. Hint: How heavy some one feels is another name for normal force. The problem therefore tells you the normal force. If you know weight and normal force, you can determine centripetal acceleration. You can substitute a value for mass if you wish.
NASA uses a machine often called the "vomit comet" to mimic the effects of low gravity in space during astronaut training. The machine moves in circular arcs at a speed of v = 214 m/s. What is the radius the pilot must fly to create weightlessness as they go around the top of the circular arc? Give your answer in meters.

Homework Problem 31: A professor is swinging a ball (Mass 0.358Kg) in a vertical circle at a constant speed. The length of the string is 0.29m. The professor measures the tension and discovers that it is 1.715 times larger at the bottom of the circle than at the top. What is the speed of the swinging mass? Note: The acceleration due to gravity is directly downwards.
