Questions & Step-by-Step Solutions
An object is thrown upwards with a speed of 20 m/s. How long will it take to reach the maximum height? (Assume g = 10 m/s²)
Step 1: Identify the initial speed of the object. In this case, it is 20 m/s.
Step 2: Identify the acceleration due to gravity (g). Here, it is given as 10 m/s².
Step 3: Use the formula to find the time to reach maximum height. The formula is: time = initial speed / g.
Step 4: Plug in the values: time = 20 m/s / 10 m/s².
Step 5: Calculate the result: 20 divided by 10 equals 2.
Step 6: Conclude that it will take 2 seconds to reach the 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 the knowledge of gravitational acceleration and its effect on the motion of the object.
