Question

an object is thrown vertically upwards and rises to a height of 5m. then the velocity with which the object was thrown upwards​

Answer 1

Explanation:

v = 0m/s

h = 5m

g = -9.8m/s²

u = ?

v² - u² = 2gh

0² - u² = 2(-9.8)(5)

- u² = (10)(-9.8)

- u² = - 98

u² = 98

u = 7√2

u = 7√2 m/s
