Q. To give a 22 kg child a ride, two teenagers pull on a 3.6 kg sled with ropes. Both teenagers pull with a force of F = 55 N at an angle of 35° relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 N. Find the acceleration of the sled and child.
What is the frequency of up and down oscillations of the wheel? Regard wheel as a mass on one end of a spring and regard the body of the car as a fixed support for the other end of the spring.
What is the terminal speed for a 76.0 skier going down a 41.0 snow-covered slope on wooden skis = 0.070? Suppose that the skier is 1.80 m tall and 0.500 m wide. Replace mg with net forces parallel to the incline.
When these two wires are connected in equivalent to the same battery, describe the reasoning of the steps that allow you to find out which of these wires will consume the greater amount of power by warming up and dissipating this energy as heat.
A 78-kg man standing on a scale in an elevator notes that as elevator rises, the scale reads 834 N. What is the acceleration of the elevator.
Two identical +9.5uC point charges are initially 3.5cm from each other. If they are released at the same instant from rest, hoe fast will each be moving when they are very far away from each other? suppose they have identical masse of 1mg.
A 38.0 kg child swings in a swing supported by two chains, each 3.04m long. The tension in each chain at the lowest point is 429N. Find out the child's speeds at the lowest point.
A cockroach of mass m lies on the rim of a uniform disk of mass 8m that can rotate freely about its center like a merry-go-round. at first the cockroach and disk rotate together with an angular velocity of 0.200 rad/s. Then the cockroach walks half..
What should be the spring constant of a spring designed to bring a 1500 car to rest from a speed of 80 so that the occupants undergo a maximum acceleration of 5.
Jane and John, with masses of 51 kg and 66 kg, correspondingly, stand on a frictionless surface 13m apart. John pulls on a rope that connects him to Jane, giving Jane an acceleration of 0.9m/s2 toward him.
What is the magnitude of the apparent weight of a 83 astronaut 4600 from the center of Earth's Moon in a space vehicle moving at constant velocity.
A rotating cylinder about 16 {rm km} long and 6.8 km in diameter is designed to be used as a space colony. With what angular speed should it rotate so that the residents on it will experience the same acceleration due to gravity as on Earth.
A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.6m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930m. At that point its engines fai..
