Answer:
10.32m/s
Explanation:
F = ma
T -mg sinθ-f =ma
We can conclude that T = 300 newtons by taking a freebody of the cable. So we need to determine only the frictional force.
f(n) = 0
mgcosθ = N = 0
N = mgcosθ
T - mg sinθ - u mgcosθ = ma
a = T - mg (sinθ + u cosθ) / m
a = 5.32m/s^2
Use constant acceleration kinematics:
= 
The gravitational force increseaes exponentially as you get closer to the moon. Since the denominator of the gravitational force formula is r^2, cutting the distance in half increases the force 4-fold.
40 km/h because the average of 50 and 30 is 40
Between the bumps and dips of two surfaces. SO the answer is 2 surfaces. Hope this helps! :)
Answer:
884Hz
Explanation:
Beats is the absolute difference between two frequencies therefore
Beats = f1-f2
4=f1-880
F1=880+4
F1=884Hz
