I have to draw a wave on a separate sheet of paper given the following measurements down below. I'm a bit confused, do I just us
e a ruler and make the crest 1 cm long across along with the trough and wave length like I did in the pic. Did I do it correctly?
Wave #1:
1 cm Crest
1 cm Trough
2 cm Wavelength

Explanation:
Given
mass of sled =26 kg
coefficient of static friction
coefficient of kinetic friction
In order to move sled from rest we need to provide a force greater than static friction which is given by
After Moving Sled kinetic friction comes in to play which is less than static friction
therefore minimum force to keep moving sledge at constant velocity is 18.34 N
The average velocity of Sandy is given by the total distance covered S divided by the total time taken t:
The total distance covered is
while the total time taken is 2 hours + half an hour (for the rest) + 1 hour and half, so
Therefore, the average velocity is
The total distance covered is
while the total time taken is 2 hours + half an hour (for the rest) + 1 hour and half, so
Therefore, the average velocity is
