What is the value of height h? 2. What is the velocity of sphere A just before it hits block B? 3. What is the length of the rope l, if α = 60°? Figure not necessarily to scale. (Hint: Use point C as datum) pls answer asap

13. A skier/snowboarder starts at rest at the top of a snowy (friction-free) hill with height h₁. After the bottom of this hill there is a small "jump" hill. The top of the jump has height h, and a curvature of radius R. What is the minimum height of the starting hill, himin, so that the skier/snowboarder jumps or "catches air" at the top of hill 2? Solve for himin in terms of h₂, R, and g. Hint: if the skier/snowboarder jumps, he/she/they loose contact with the snowy ground. h₁ to jump!

Pls solve this question quickly and 100% correct. Also could you do it handwritten for me to better understand thank you. A small airplane starts flying at a constant speed of 281 km/h on a heading of N79W. A 68 km/h wind is blowing from N13E. Determine the ground velocity of the airplane. Give direction as a quadrant bearing. Include diagram showing the vector addition with your solution.

1. Consider Figure 1 above. What if the ball is kicked off from the top of the building, with height h, at an angle 0; and with an initial velocity v; at point A. a. Draw the velocity at each point together with its components.
