Problem 15.3 Motorcycle Ramp
A slope of a motorcycle ramp is defined as the ratio (or comparison)
between the vertical rise and the horizontal run when riding between two
points on the ramp. That is:
1c. What angle to the nearest minute is made by a ramp of
maximum allowable slope?
2a. Find the distance that the rider will cover on the following
ramp (i.e. calculate BE).
2c. The rider moves at a constant speed of 30 km/h on the ramp.
How long is he on the ramp for? Round your answer to the nearest second.
2d. Calculate the length of the diagonal AE. |
