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.
