Answer:
9.4 m
Explanation:
This is a projectile motion. The maximum height above the level projection is given by
is the initial velocity, is the angle of projection above the horizontal and is the acceleration of gravity.
The maximujm height above the ground is 1 m + 8.4 m = 9.4 m
Answer:
4 cm/s
Explanation:
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed (and speed in general) can be represented by the equation:
Speed = Distance/Time
Sound and light, as well as all other types of mechanical and electromagnetic
radiation, travel as waves. They all carry energy from place to place.
