- A block slides down a frictionless plane that makes an angle of 30° with the horizontal. The acceleration of the block is: none of the given choices O 566 cm/s² O 849 cm/s² O 980 cm/s² O 490 cm/s²=. Consider a skydiver falling towards the Earth. Air friction acts to oppose their motion. At some point the skydiver reaches their terminal speed: their constant maximum speed (before they open the parachute). Before and after terminal speed is reached, what can you say about the relationship between the force of air friction and the force of gravity? Briefly explain.A 61.0 kg box hangs from a rope. What is the tension in the rope if: the box moves up at a steady 5.40 m/s?; The box has vy = 4.80 m/s and is speeding up at 5.50 m/s2 if the y-axis is pointing upward?; The box has vy = 4.80 m/s and is slowing down at 5.50 m/s2?
- You are standing on a scale inside an elevator (near the Earth's surface) just to weird people out. You know that you weigh 600 N. The scale reads 550 N. Which of the following statements can you make about the motion of the elevator based on this information? Select all that apply. The elevator has zero velocity. The elevator has zero acceleration. × The elevator's velocity points upwards. Selected Answer - Incorrect × The elevator's acceleration points upwards. Selected Answer - Incorrect The elevator's velocity points downwards. The elevator's acceleration points downwards.At a given instant in time, a 12kg rock is observed to be falling with an acceleration of 6.25m/s2 (Note that this is different from the gravitational acceleration. This difference must be due to another force, air resistance, pushing up on the rock. What is the magnitude and direction of the net force on the rock? What is the magnitude and direction of the gravitational force acting on the rock? What is the magnitude of the force of the air resistance acting on the rock at this instant?7.) Please help with equation, gravity is g=32.2 ft/sec^2 or g=9.81 m/sec^2
- If the man pulls the strap with constant acceleration during a short time interval At, calculate the force (in Newtons) that he must exert in spinning up the disc. These are the numbers. Strap's final speed = v = 1.4 m/s. The disc's radius is R = 1 m %3D The small disc's radius is 3 cm The disc's mass is M = 2.3 kg The short time interval is At = 0.5 s The disc initially is non-rotating.A person stands on a scale inside an elevator at rest. The scale reads W= 666N . The elevator accelerates upward momentarily at the rate of a= 4 m/s2 What does the scale read then?Three boxes are shown below. The label in each box shows its mass. The distance between Box A and Box B is the same as the distance between Box B and Box C. Which two boxes have the greatest gravitational force between them?

- If a ball having mass m= 200g is attached to a light string that is 50 cm long is travelling at 3.00 m/s at the bottom of the vertical, circular path, what is the tension in the string at that moment? (Take g=10m/s³) 5,6 N 1,6 N 3,6 N 38 N 34 NConsider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.27 m/s2 and the person has a mass of 79.2 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.If a 1200-kg car starts from Point A and drives uphill with a curvature given by y = 0.00001 x³, where x and y are in metres, at a constant speed of 100 km/hr, what is the car's velocity in when it reaches 300 m in the horizontal direction? What are the forces acting upon it m S at that point in terms of the x- and y-coordinate system? A
