6. The neighborhood kids have built a ramp 1.00 m tall with an angle of 30.0% to the horizontal. One of the kids can get up to 7.00 m/s on flat ground before starting up the ramp. Assume rolling friction is neglible. (a) What is the speed of the bike when it leaves the top of the ramp? (3) (b) Using a vertical-horizontal Cartesian coordinate system, what is the velocity of the bike in component form? (3) (c) How long does the bike spend in the air? (2) (d) How far does the bike travel horizontally before it hits the ground? (2) 6. The neighborhood kids have built a ramp 1.00 m tall with an angle of 30.0% to the horizontal.

Answer rating: 100% (QA)

a To find the speed of the bike when it leaves the top of the ramp we can use the principles of conservation of energy The initial kinetic energy of the bike on flat ground will be equal to the sum of ... View the full answer
