A roller coaster car is going over the top of a 18-mm-radius circular rise. At the top of the hill, the passengers "feel light,"

Andre45 [30]

Answer:

0.29713 m/s

Explanation:

m = Mass of person

g = Acceleration due to gravity = 9.81 m/s²

v = Velocity

r = Radius = 18 mm

By balancing the forces in the system we have

$mg-N=\dfrac{mv^2}{r}\\\Rightarrow mg-\dfrac{mg}{2}=\dfrac{mv^2}{r}\\\Rightarrow v=\sqrt{r(g-\dfrac{g}{2})}\\\Rightarrow v=\sqrt{0.018\times (9.81-\dfrac{9.81}{2})}\\\Rightarrow v=0.29713\ m/s$

The velocity of the coaster is 0.29713 m/s

How many cubic feet are in a 55-gallon drum?

san4es73 [151]

1 gallon = 231 cubic inches
1 cubic foot = 1728 cubic inches

   (55 gal) x (231 in³/gal) x (1 ft³/1728 in³)

   = (55 x 231 / 1728) ft³

   = 7.352 cubic feet (rounded)

Calculate the force exerted by a mental ball having a mass of 70kg moving with speed of 20m/s>2

lord [1]

Answer:

F = 1400 N

Explanation:

It is given that,

Mass of the ball, m = 70 kg

It is moving with an acceleration of 20 m/s². We need to find the force exerted by the ball.

Force is given by the product of mass and acceleration. So,

F = ma

$F=70\ kg\times \ 20m/s^2\\\\F=1400\ N$

So, the force of 1400 N is exerted by a metal ball.
