A skateboarder rolls down Beach Avenue with an initial velocity of 3.5 m/s. If her acceleration is 1.5 m/s, how long will it take her to reach the bottom 120m away?

Final answer:

To find the time it takes for the skateboarder to reach the bottom, we can use the equation: distance = initial velocity × time + 0.5 × acceleration × time^2.

Step-by-step explanation:

To find the time it takes for the skateboarder to reach the bottom, we can use the equation:
distance = initial velocity × time + 0.5 × acceleration × time2

This is because wavelength and frequency have an inverse relationship since all electromagnetic waves travel at the speed of light. The energy of an electromagnetic wave is directly proportional to its frequency and inversely proportional to its wavelength.

Plugging in the given values, we have:

120 = 3.5 × t + 0.5 × 1.5 × t2

This is a quadratic equation that we can solve for t. Once we find the time, we can determine how long it takes for the skateboarder to reach the bottom.
