A ball is thrown upwards with an initial velocity of 20 m/s. How long will it take to reach the maximum height? (g = 10 m/s²)

A ball is thrown upwards with an initial velocity of 20 m/s. How long will it take to reach the maximum height? (g = 10 m/s²)

Step 1: Understand that when a ball is thrown upwards, it will eventually stop rising and reach its maximum height before falling back down.
Step 2: Know that the initial velocity (v) of the ball is 20 m/s.
Step 3: Recognize that the acceleration due to gravity (g) is 10 m/s², which acts downwards.
Step 4: Use the formula to find the time (t) it takes to reach maximum height: t = v / g.
Step 5: Substitute the values into the formula: t = 20 m/s / 10 m/s².
Step 6: Calculate the time: t = 2 seconds.

Kinematics – The study of motion, particularly the equations that describe the motion of objects under the influence of gravity.
Maximum Height – The highest point reached by an object thrown upwards, where its velocity becomes zero before it starts descending.
Acceleration due to Gravity – The constant acceleration experienced by an object in free fall towards the Earth, typically denoted as 'g'.
