Question

What is the theoretical value for the ball's average speed, again assuming that the ramp is at a 2o angle with a 2.5 m length? Answer in meters per second.

a) 2.13 m/s
b) 3.75 m/s
c) 4.92 m/s
d) 5.67 m/s

Answer 1

The theoretical value for the ball's average speed on a ramp with a 20-degree angle and a length of 2.5 meters is 1 m/s.

Step-by-step explanation:

To find the theoretical value for the ball's average speed on a ramp with a 20-degree angle and a length of 2.5 meters, we can use the formula:

average speed = total distance / total time

In this case, the total distance is the length of the ramp, which is 2.5 meters. The total time can be found by dividing the distance the ball travels up the ramp by its velocity. Since the ball takes the same amount of time to rise as it does to fall, the total time is 2.5 seconds.

Therefore, the theoretical value for the ball's average speed is:
