- Block B, in the figure below, weighs 100 kg. The coefficient of friction () between Block B and the floor is 0.4. Pulley A has a radius of gyration (k) of 0.5 m, it has a mass of 300 kg (I-mk-) and a diameter of 15m. The system starts from rest. Neglect the weight of the cable. A constant force (P) of 1000 N is applied. Using the incrtia method of Chapter 13 determine: a) the angular acceleration of Pulley A b) the tension in the cable 100 kg B. 30 300 kg k-0.5m Dia-1.5 mDetermine the distance X the 84.0 N force F 2 should be applied inorder to balance force F 1 of 24.0 N, which is 75.0 cm from thecenter of rotation.A roller-coaster vehicle has a mass of 455 kg when fully loaded with passengers (see figure). 10 m/ 15 m (a) If the vehicle has a speed of 22.0 m/s at point O, what is the forke (in N) of the track on the vehicle at this point? (b) What is the maximum speed (in m/s) the vehicle can have at point ® in order for gravity to hold it on the track? m/s
- (c) Determine the tensions in the string on both sides of the pulley.Please sketch a free body diagram thank you very muchA small child of mass m = 38 kg is swinging on a swing. The length from the upper bar of the swing set to the seat is L = 4.4 m. The kid is attempting to swing all the way around in a full circle. Assuming the kid is traveling at the speed found in part (a), what is their apparent weight, Wa in newtons, at the top of their path? (At the top, the kid is upside-down.)
