Answer:

The kinetic energy of the roller coaster is 1600000 J.

Step-by-step explanation:

Given:

Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.

Now, we need to find the kinetic energy E_{k} of the roller coaster.

So, Mass of roller coaster (m) = 8000 N.

Velocity of roller coaster (v) = 20.0 m/s.

Now, putting the formula of kinetic energy:

E_{k} = \frac{1}{2}\times m\times v^{2}

E_{k}=\frac{1}{2} \times 8000\times 20^{2}

E_{k}=\frac{1}{2} \times 8000\times 400

E_{k}=\frac{1}{2} \times 3200000

E_{k}=1600000

Therefore, the kinetic energy of the roller coaster is 1600000 J.

Answer:

17.0

Step-by-step explanation:

If you take the sin(39) or cos(51), it is equal to BC/27. Multiply by 27 on both sides to get 27cos(51) or 27sin(39)= x. Plug into the calculator, and voila.

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one sam
____ [38]
We can set up 2 equations given the information.
Let the price of advance ticket be represented by A and same day ticket by S

A + S = 50
20A + 40S = 1700

Solve for A in the first equation by subtracting S on both sides.
U will get A = 50 - S

Now substitute 50 - S for A in the second equation.

20 (50 - S) + 40S = 1700
1000 - 20S + 40S = 1700
20S = 700
S = 35

Same day ticket costs $35 and advance ticket costs $15
