Can someone please explain how to solve 13?
frozen [14]

Hello!

Everything you've done so far seems to be correct. However, you need to get rid of the sin. To do this, use ssin^{-1}.

This is known as the inverse of sin, which is where you go from a fraction to the actual angle itself.

When you run sin^{-1}(1/5) through a calculator, you get about 11.537 degrees, or θ = 11.537.

To verify this, all you need to do is run sin (11.537), and the calculator returns 0.2, which is what we're looking for.

Hope this helps!

With each bounce off the floor, a tennis ball loses 18% of its mechanical energy due to friction. When the ball is released from
lora16 [44]

Answer:

130 cm

Explanation:

After each bounce, the mechanical energy decreases by 18%, which means the maximum height decreases by 18%.  Modeling this as exponential decay:

h = 290 (1 − 0.18)ⁿ

h = 290 (0.82)ⁿ

h = 290 (0.82)⁴

h = 130

The ball reaches a height of 130 cm.
