A roller coaster accelerated from rest to 55 m/s by the time it reached the first hill. The roller coaster took 15 seconds to cl
GalinKa [24]

Answer:

I believe the acceleration is 3.66666666667 m/s

Step-by-step explanation:

Acceleration formula: a = vf - vi / t

Initial velocity: 0 (I believe it was 0, as it wasn't moving in the beginning)

Final velocity: 55 m/s

Time: 15 s

Substituting values: 3.66666666667 = 55 - 0 / 15

draw and label a parallelogram with a base twice as long as the height and an area less than 60 square inches. find the area
liubo4ka [24]
Answer: 5 cm by 10 cm gives an area of 50 cm^2

To do this draw a parallelogram and start by labeling the base as 10 cm. If 10 cm is the base, then the height needs to be 5 cm.

To find the area, multiply the base times height.

This will give you: 5 x 10 = 50 which is less than 60.
