Anew ride being built at an amusement park includes a vertical drop of 126.5 meters. starting from rest, the ride vertically drops that distance before the track curves forward. if friction is neglected, what would be the speed of the roller coaster at the bottom of the drop?

17.60 m/s
24.90 m/s
49.79 m/s
70.42 m/s

49.79 m/s

Explanation:

Given:

Initial velocity of the roller coaster is,

Vertical drop or the displacement of the roller coaster is,

The displacement is negative as the motion is in downward direction.

Now, as the motion is in vertical direction only, the acceleration of the roller coaster will be due to gravity acting in the downward direction.

So, the acceleration of the roller coaster is,

Now, using the following equation of motion:

Where, 'v' is the velocity of the roller coaster at the bottom.

Plug in all the given values and solve for 'v'. This gives,

Therefore, the speed of the roller coaster at the bottom of the drop is 49.79 m/s.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
