Exam 2 Study Guide PHY 230-20 – Dr. Dirk Pandel By Caleb Alves Topics covered:  Circular Motion  Newton’s Laws of Motion  Applying Newton’s Laws  Work + Energy 1) Spider-man has a mass of 80 kg and leaps from a building. He shoots a web to an adjacent building 14 meters away perpendicular to his position. He swings a half circle and releases when he’s level with his original position with a velocity of 8 m/s. Calculate the centripetal force of Spidey’s swing and determine the source of the force. 2) A car of mass 824 kg drives around a banked loop of radius 12 meters and experiences a centripetal force of 2,168 N. Calculate the angle of the banked curve. Page 1 3) Consider the inclined Atwood machine with a massless string and frictionless pulley, and with α = 31 , µ =k0.089 and m = 2.241kg as m accelerate1 at 2 1.3 m/s up the ramp. Calculate the tension in the rope, and determine the mass of m . 2 Page 2 4) Your friends are building a lightning bolt sculpture to hang in your school’s gymnasium. The sculpture weighs 145 N, and they want to hang it with steel cables on the ceiling, but want to make sure that it’s not going to fall. If a and o b both equal 18 , calculate the tension in the ropes. 5) A mass hangs from a spring attached to the ceiling. If the spring’s force constant is 310 N / m and it’s displaced 0.15 m, what is the mass of the object? Page 3 6) The star Alpha Centauri exerts a varying force modeled by the function N F(t= ( ) s t−0.32 on a nearby asteroid falling into the star. If the asteroid were on Earth, it would weigh 104,321 N. Calculate the velocity of the asteroid after 15 minutes. 7) Once a rocket leaves Earth’s atmosphere, the force exerted by gravity follows F(x)= −1 x+2.77 the function 15.65 (not really, just made that up). Calculate the work done by Earth’s gravity on the rocket from when the rocket first leaves Earth to when it’s 5 miles away. (Hint: displacement is opposite the direction of the force, causing work to be negative). Page 4 8) A modified nerf gun has a spring with a force constant of 250 N/m. Just before firing, the spring has an elastic potential energy of 22.5 J. Assuming the spring transfers 100% of the energy and the barrel is frictionless, calculate the speed of a 0.5 kg dart fired from the gun. Page 5
