- A roller coaster contains a loop-the-loop in which the car and rider are completely upside down at the top of the loop. The radius of the loop is 16 m. What minimum speed (in m/s) must the car have at the top so that the rider does not fall out while upside down? Assume the rider is not strapped to the car. 12.53 m/s. What is the magnitude of the normal force at the top of the loop? What is the magnitude of the normal force at the bottom of the loop?OK, same sort of track, but now with d = 2.80 m. Now suppose the blocks starts on the track at x = 3.20 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? 8.47 m/s 5.99 m/s 10.12 m/s 4.83 m/sTarzan grabs a vine hanging vertically from a tall tree when he is running at 9.3 m/s. a. How high (in m) can he swing upward? (Enter your answer with respect to the ground.) (Answer in m) b. Does the length of the vine affect this height? (Yes or No)
- A roller coaster cart is moving over the top of a circular hill that has a diameter of 56 m. What is the fastest safe speed that the roller cart can go over the top of the hill? (that is, at what speed will the cart begin to lose contact with the track?). Assume a coefficient of friction of 0.7.A projectile is fired from a point 50 meter from a tall cliff at 75 m/sec and at angle of 50 degrees above the horizontal. It will strike the cliff at a point h above the cliff base. What is h? What is the final speed of the projectile when it hits the cliff in the problem above?A mother pushes her child on a swing so that his speed is 9.7 m/s at the lowest point of his path. The swing is attached to a point 2.05 m above the child’s center of mass when the swing is motionless. What is the centripetal acceleration of the child at the low point in m/s2? What is the magnitude of the force that the child exerts on the seat at the lowest point if his mass is 19.5 kg in N?
- A 1.0 kg ball at the end of a 2.0 m string swings in a vertical plane. At its lowest point the ball is moving with a speed of 10 m/s.What is the tension, in newtons, in the string when the ball is at the top of its path?A BMX biker wanted to impress his family by catching some air( aka leaving the ground) while riding over a hill in Tennesse with a radius of curvature of 7.6m. If the BMX biker rides over the hill at 11.2 m/s, will she catch some air and excitee her family? B) What is the minimum speed the biker has to travel in order to leave the ground when cresting the hill?why would it be +1/2gt instead of -?
