Question

richard rides a bike on a road sloping downward and inclined at an angle of 30° with the horizontal. if he moves at a constant speed of 10 meters/second, calculate his vertical downward velocity.
a. 2.5 meters/second
b. 5.0 meters/second
c. 8.7 meters/second
d. 10.5 meters/second

Explanation:

Step1: Identify given values

θ = 30°, v = 10 m/s

Step2: Calculate vertical velocity

v_vertical = v sinθ = 10 sin30° = 10 * 0.5 = 5 m/s

Answer:

B. 5.0 meters/second
