A ball is thrown upwards with a speed of 20 m/s. How long will it take to reach the maximum height? (Take g = 10 m/s²) (2023)

A ball is thrown upwards with a speed of 20 m/s. How long will it take to reach the maximum height? (Take g = 10 m/s²) (2023)

Step 1: Understand that when a ball is thrown upwards, it will eventually stop rising and reach a maximum height before falling back down.
Step 2: Know that the initial speed of the ball is 20 m/s.
Step 3: Recognize that gravity (g) pulls the ball down at a rate of 10 m/s².
Step 4: To find out how long it takes to reach the maximum height, use the formula: Time = Initial Velocity / g.
Step 5: Plug in the values: Time = 20 m/s / 10 m/s².
Step 6: Calculate the time: 20 divided by 10 equals 2 seconds.
Step 7: Conclude that it takes 2 seconds for the ball to reach its maximum height.

Projectile Motion – The question tests understanding of the basic principles of projectile motion, specifically the time taken to reach maximum height when an object is thrown vertically upwards.
Acceleration due to Gravity – It assesses knowledge of gravitational acceleration and its effect on an object's motion when thrown upwards.
