A girl throws a stone with an initial velocity of 4.44 m/s at 60.7° above the horizontal. If air resistance is negligible, after how much time tmax does the stone reach its maximum height? tmax S

A 2.75 kg box slides UP a smooth (frictionless) 39-degree hill with an initial speed of 18.0 m/s. To what maximum height above the bottom of the hill does the box reach before stopping?

The known elevations of a toy rocket trajectory are as follows: hA = 15 ft hg = 34 ft hc = 15 ft Assuming that the rocket is coasting and friction is negligible (energy is conserved), which of the statements below is true? В C A hB hc hA O The velocity at position A will be greater than the velocity at position C The velocity at position B will be greater than the velocity at position A The velocity at position A will be equal to the velocity at position B The velocity at position A will be equal to the velocity at position C

Consider the frictionless water slide in the figure below. h₁ h₂ 1. If a 12.00kg dog starts from rest and slides down the water slide and has a velocity of 2.00 in the horizontal direction at point A, determine the height h₁ of the slide. m S m 2. If the bottom of the slide (point A) is 5.00m above the water level, how far horizontally does the dog travel between point A and when it reaches the water at point B? m оо B 3. How would increasing the mass of the dog impact your calculations above? It would result in the height of the slide being greater It would result in the height of the slide being less Equal Less than It would result in the dog's horizontal distance being greater It would result in the dog's horizontal distance being less It wouldn't impact any of the calculations 4. If the slide had friction, would the dog's velocity at point A be greater than, less than, or equal to the velocity without friction? Greater than
