The distance between the resting point and maximum height of the wave is 0.2 cm.
The amplitude is measured from the resting point up to the highest point of the wave.
Work = Force * distance
Work = 40N * 10m
Work = 400N
Answer:
10 cos (30)N
Explanation:
So, if we were to visualize it for a sec
we would see 10 as the hypotenuse, 30 as the angle between and would be solving for the adjacent side
So, using basic trig rules,
using the fact that cos(30)=x/10
x=10 cos (30)N
Concave makes things smaller and convex makes things bigger
