Q
Q: A stone is thrown vertically upward with a speed of 20 m/s. How long will it take to reach the maximum height?
Solution:
Time to reach maximum height = initial velocity / g = 20 / 10 = 2 s.
Steps: 7
Show Steps
Step 1: Understand that when a stone is thrown upward, it will eventually stop rising and reach a maximum height before falling back down.
Step 2: Know that the initial speed of the stone is 20 m/s.
Step 3: Remember that the acceleration due to gravity (g) is approximately 10 m/s², which acts downward.
Step 4: To find the time 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 will take 2 seconds for the stone to reach its maximum height.
