Question

part a: calculate the average speed for the short, medium, and long ramps. fill in the average speed in the data chart.

	ramp length (meters)	time (seconds)	average speed (m/s)
medium ramp	6	3
long ramp	9	3.6

Explanation:

Step1: Recall speed formula

The formula for average speed is $v=\frac{d}{t}$, where $v$ is average speed, $d$ is distance (ramp - length here) and $t$ is time.

Step2: Calculate average speed for short ramp

For the short - ramp, $d = 3$ meters and $t = 2$ seconds. Using the formula $v=\frac{d}{t}$, we have $v_{1}=\frac{3}{2}=1.5$ m/s.

Step3: Calculate average speed for medium ramp

For the medium - ramp, $d = 6$ meters and $t = 3$ seconds. Using the formula $v=\frac{d}{t}$, we get $v_{2}=\frac{6}{3}=2$ m/s.

Step4: Calculate average speed for long ramp

For the long - ramp, $d = 9$ meters and $t = 3.6$ seconds. Using the formula $v=\frac{d}{t}$, we obtain $v_{3}=\frac{9}{3.6}=2.5$ m/s.

Answer:

Ramp Type	Average Speed (m/s)
Medium Ramp	2
Long Ramp	2.5
