Question

A stone is thrown vertically upward with a speed of

a) 2² m/s
b) 5 m/s
c) 10 m/s
d) 15 m/s

Answer 1

The stone's maximum height can be determined using equations of motion.

Step-by-step explanation:

In this problem, a stone is thrown vertically upward with a given speed. We can use the equations of motion to determine the maximum height reached by the stone and the time it takes to reach that height.

When a stone is thrown straight up, the initial velocity and acceleration due to gravity are considered to be positive in the upward direction. So, the stone will slow down and eventually come to a stop at its maximum height before falling back down.

The maximum height reached by the stone can be calculated using the formula:

maximum height = (initial velocity)^2 / (2 * acceleration due to gravity)

Substituting the given values for the initial velocity (2² m/s, 5 m/s, 10 m/s, or 15 m/s) and the acceleration due to gravity (9.8 m/s²), we can find the maximum height.
