A stone is thrown vertically upward with a speed of 20 m/s. How long will it take to reach the maximum height? (g = 10 m/s²)

A stone is thrown vertically upward with a speed of 20 m/s. How long will it take to reach the maximum height? (g = 10 m/s²)

Step 1: Identify the initial speed (u) of the stone, which is 20 m/s.
Step 2: Recognize that at the maximum height, the final speed (v) of the stone will be 0 m/s.
Step 3: Use the formula v = u - gt, where g is the acceleration due to gravity (10 m/s²) and t is the time in seconds.
Step 4: Substitute the known values into the formula: 0 = 20 - 10t.
Step 5: Rearrange the equation to solve for t: 10t = 20.
Step 6: Divide both sides by 10 to find t: t = 20 / 10.
Step 7: Calculate the result: t = 2 seconds.

Kinematics – The study of motion, specifically how objects move under the influence of forces, including the equations of motion for objects in free fall.
Acceleration due to Gravity – Understanding that objects in free fall experience a constant acceleration downwards, typically denoted as 'g'.
Maximum Height in Projectile Motion – The point at which the vertical velocity of the object becomes zero before it starts descending.
