Mar 11, 2013 · A stone is thrown with an initial speed of 15 m/s at an angle of 53 above the horizontal from the top of a 35 m building. If ax = 0, ay = - g = - 9.8 m/s2 and air resistance is negligible, then what is the magnitude of the vertical velocity-component of the rock as it hits the ground? helppppp , and please give me details so i can understand it !! thanks in advance <3

If you match the existing edge angle and hold the knife against the stone to cut evenly across the edge grind, you will produce an edge with a similar angle. A good rule of thumb is to hold the blade so the back of it is about one blade width up from flat on the stone.
Do your answers change if the pebble was thrown at an angle of 45° with the horizontal direction 1 Ignore air resistance. Answer: (a) When the pebble is moving upward, the acceleration g is acting downward, so the force is acting downward is equal to F = mg = 0.05 kg x 10 ms -2 = 0.5 N.
Sep 08, 2014 · The distance in feet between the stone and the ground in 't' seconds is given by the function h (t) = -16t(t) -4t+ 442. How long after the stone is thrown is it 430 feet from the . Physics. A stone is projected upward at an angle of 30 degree to the horizontal from the top of a tower 100m and it hits the ground at a point q.
Spyderco’s Tri-Angle Sharpmaker takes the mystery out of this process and enables anyone to sharpen a knife effectively with just a few minutes practice. Its durable ABS plastic base contains keyed holes that accurately set the stones’ sharpening angles at a 30° (15° each side) or 40° (20° each side) for sharpening knives.
Question 12 2.5 pts A stone is thrown from the top of a building upward at an angle of 8 = 30° to the horizontal with an initial speed of vas shown in the Figure. The distance from the building just before it strikes the ground is d = 160.8 m.
