Question:

should i get some road tyres for my specialized rock hoper comp ?

ts just i have large bulky tyres which when i cycle on roads a feel like they take a lot of effort! i don't know if it would be simpler to change them or have a separate set?? also im 18 so some that don't coast an arm and a leg???

Answer:

most street-bike helmets are full-faced with a facesheild. Most dirtbike helmets are full-faced with no facesheild so the rider can wear goggles. most streetbike helmets are SNELL approved, while most dirtbike helmets are DOT approved, if anything. If you've got a streetbike, get a SNELL-approved street helmet. For a dirtbike, the dirtbike helmets are fine.
I'll treat the water as a projectile and ignore any effects of surface tension. I'll also ignore atmospheric drag. I'll also assume that the earth is flat and that gravity is fixed at 9.81m/s?. Lastly I'll assume that the hose is at ground level. All these assumptions should be quite accurate in this situation. I'm not sure which equations of motion you can simply assume. There is a simple equation for the range of a projectile which is r v?sin(2θ)/g. We know r, v, and g, so: sin(2θ) 2 * 9.81 / 44.89 0.437 We want solutions in the first quadrant, so 0 2θ 180 2θ 25.92 and 154.08 θ 12.96 and 77.04 There are two angles that hose can be aimed, one fairly low to the ground and one aimed quite near the vertical.
move it quickly up and down the rod without clicking.
