Question
How long will it take for a stone thrown vertically upward with an initial velocity of 20 m/s to reach its highest point?Select one:a.1.5 sb.4.0 sc.2.04 sd.3.0 s
Solution
The time it takes for an object thrown upward to reach its highest point can be calculated using the formula:
t = v / g
where:
- t is the time,
- v is the initial velocity, and
- g is the acceleration due to gravity.
Given that the initial velocity (v) is 20 m/s and the acceleration due to gravity (g) is approximately 9.8 m/s², we can substitute these values into the formula:
t = 20 / 9.8
This gives us a time of approximately 2.04 seconds. So, the correct answer is c. 2.04 s.
