A ball rolls at a constant velocity of 1.50 m/s at an angle of 45o below the in the fourth quadrant. If we take the ball to be at the origin at t = 0 what are its coordinates (x, y) 1.65 s later?
Answer to relevant QuestionsYou are in a fast powerboat that is capable of a sustained steady speed of 20.0 m/s in still water. On a swift, straight section of a river you travel parallel to the bank of the river. You note that you take 15.0 s to go ...A hockey puck slides along a horizontal ice surface at 20.0 m/s, hits a flat vertical wall, and bounces off. Its initial velocity vector makes an angle of 35o with the wall and it comes off at an angle of 25o moving at 10.0 ...A 75.0-kg person is standing on a scale in an elevator. What is the reading of the scale in newtons if the elevator is (a) At rest, (b) Moving up at a constant velocity of 2.00 m/s, and (c) Accelerating up at 2.00 m/s2? A block of mass 25.0 kg slides down a frictionless surface inclined at 30°. To ensure that the block does not accelerate, what is the smallest force that you must exert on it and what is its direction? Referring to Fig. 4.41, what are the tensions in all the cords?
