- You are playing a game and you push a cart to give it in. speed. The cart starts at the bottom (zero) of a ramp and after reaching the top of the ramp, the cart travels across a horizontal track w/ friction. The mass of the cart is 44 x 10^-3 kg. The ramp is 56 cm high. The length is 70 cm. What can you infer of the intial speed in (m/s)Jeff of the Jungle swings on a 7.6-m vine that initially makesan angle of 37° with the vertical. If Jeff starts at rest and has amass of 78 kg, what is the tension in the vine at the lowest pointof the swing?Express the 2 forces in CVN then determine the resultant force in N generated at point A which is located at (6,10,0) ft. 8ft C 8ft 6ft .... 200 Ib 100 Ib A
- An adventurous archeologist (m = 85.0 kg) tries to cross ariver by swinging from a vine. The vine is 10.0 m long, and hisspeed at the bottom of the swing is 8.00 m/s. The archeologistdoesn’t know that the vine has a breaking strength of 1 000 N.Does he make it across the river without falling in?Caroline takes her baby sister Hannah to the neighborhood park and places her in the seatof the children’s swing. Caroline pulls the L = 1.8 m long chain back to make an angle θ = 26◦ withrespect to the vertical and lets 14 kg Hannah (swing mass included) go. (a) Determine Hannah’s speed at the lowest point in the trajectory. (b) What is the tension in the swing chain at this low point? Assume the chain itself has negligible mass.The figure shows a block of mass m resting on a 20o slope. The block has coefficients of friction us=0.64 and uk=0.54 with the surface of the slope. It is connected using a very light string over an ideal pulley to a hanging block of mass 2.0 kg. The string above the slope pulls parallel to the surface. What is the minimum mass m so the system will remain at rest when it is released from rest?
- A movie stunt performer is filming a scene where he swings across a river on a vine. The safety crew must use a vine with enough strength so that it doesn't break while swinging. The stunt performer's mass is 90.0 kg, the vine is 11.0 m long, and the speed of the stunt performer at the bottom of the swing has been determined to be 7.40 m/s. What is the minimum tension force (in N) the vine must be able to support without breaking? Aa N Need Help? Read Itbox with mass m goes down a ramp that makes an angle of 60 º with the horizontal. The ramp bands together to a flat section and then onto a circle track of radius R that ends where it's vertical. box is released from rest at a distance 3R above the horizontal and leaves the track at point A. all surfaces are frictionless. What force does the track exert on the box before it leaves the track?Two blocks with masses m1 = 5 kg and m2 = 15 kg are connected by a rope as shown. Thehorizontal surface is smooth and the pulley is weightless and frictionless. If the block starts fromrest, what is the speed of m2 after it has fallen by 6 m. Ans. 9.40 m/s
