Answer:
t = 4.08 s
Explanation:
if the body is thrown upward, it has negative gravity. Knowing through the International System that the earth's gravity is 9.8 m/s²
Data:
- Vo = 40 m/s
- g = -9.8 m/s²
- t = ?
Use formula:
- [tex]\boxed{\bold{t=\frac{-(V_{0})}{g}}}[/tex]
Replace and solve:
- [tex]\boxed{\bold{t=\frac{-(40\frac{m}{s})}{-9.8\frac{m}{s^{2}}}}}[/tex]
- [tex]\boxed{\boxed{\bold{t=4.08\ s}}}[/tex]
Time taken by it to reach max height is 4.08 seconds.
Greetings.
