Answer:

Step-by-step explanation:

Let the speed of the roller coaster at the bottom is v.

radius, r = 47 m

Let the mass is m and the force at the bottom is 2.5 times the weight.

F = 2.5 mg

So, the force is

F = mg + \frac{mv^{2}}{r}

2.5 mg= mg + \frac{mv^{2}}{r}

1.5g=\frac{v^{2}}{r}

v² = 1.5 gr

v² = 1.5 x 9.8 x 47

v = 26.3 m/s

Doug earns $10.50 per hour working at a restaurant. On
alexira [117]
First, add all of the working hours.
1 \frac{3}{4} + 2 \frac{1}{3} + 1 \frac{5}{12}

Since the denominators are different, make them all the same.
1 \frac{9}{12} + 2 \frac{4}{12} + 1 \frac{5}{12}

Add everything together.
4 \frac{1}{12} + 1 \frac{5}{12} = 5 \frac{6}{12}

Then, simplify.
5 \frac{1}{2} or 5.5

Multiply the time by the salary.
<span>5.5*10.5= Doug earned $57.75</span>
