<span>momentem = mass * velocity also, be sure to use the carrot for exponents 10^3 and 10^4. 20000/1200 = 16.7,This is your answer,That was hard lol.

Hope the helps.

We know, Momentum = Mass * velocity
2 * 10⁴ = (1.20 * 10³) (v)
v = 2 * 10⁴ / 1.20 * 10³
v = 1.67 * 10
v = 16.7 m/s

In short, Your Answer would be Option C

Hope this helps!

A(n) 30 kg boy rides a roller coaster. The acceleration of gravity is 9.8 m/s 2 . With what force does he press against the seat

forsale [732]

Answer:

Force, F = 187.42 N

Explanation:

It is given that,

Mass of boy, m = 30 kg

Acceleration due to gravity, $a=9.8\ m/s^2$

Radius of curvature of the roller coaster, r = 15 m

Speed of the car, v = 7.3 m/s

The force acting on the boy are force of gravity and the centripetal force. The net force acting on him is as follows :

$F=mg-\dfrac{mv^2}{r}$

$F=m(g-\dfrac{v^2}{r})$

$F=30\times (9.8-\dfrac{(7.3)^2}{15})$

F = 187.42 N

So, he press against the seat with a force is 187.42 N. Hence, this is the required solution.

1) 4°C : It has the highest density as shown on the graph.

2) Water expands when it freezes, making it less dense than just water.

3) The ice would sink to the bottom, then the rest of the water would freeze as well, the entire lake/river/whatever will freeze eliminating the organisms that live there.
