Explanation:
a) We need to write down first Newton's 2nd law as applied to the given system. The equations of motion for the x- and y-axes can be written as follows:
From Eqn(2), we see that
so using Eqn(3) on Eqn(1), we get
Solving for the acceleration, we see that
b) Now that we have the acceleration, we can now solve for the velocity of the crate at the bottom of the plane. Using the equation
Since the crate started from rest, 
Thus our equation reduces to
34 + 3.7395 = 37.7395
The answer is 38.
The answer is written to two significant figures because the smallest given number of significant figure is 2.
Answer:
If the boat is going 36 km/h, then it will take about 5.8 hours to travel a distance of 210 km/h.
Explanation:
To calculate time, you have to divide the distance by the speed.
In this case, we take 210 and divide it by 36. The answer you will get is 5.83...
There is something wrong, 56 supposed to be 5/6 and 7575 is only 75 passengers.
So to solve for this problem:If an airplane carries 75 passengers and if it is 5/6 of the capacity which is x, then we can say that:
5/6 * x = 75
5x/6 = 75
5x = 75 x 6
5x = 450
5x/5 = 450/5
x = 90
The capacity of the airplane is 90
