Which launch angle would give you a largest height in projectile motion? 90°
60°
45°
25°

90 degrees

Explanation:

Using the equation D=, the final velocity is 0 m/s at its highest point, and its initial velocity is Vi*sin(theta). Plugging this in, you will get . In this case, to get the largest value of D, you want sin(theta) to be its largest value. We can do this by changing the angle. Sin(theta) is at its largest value of 1 when you plug in sin(90). As a result, the angle which would result in the largest height would be 90 degrees.

newton's first law of motion

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
