Question

An object is thrown vertically upwards and rises to height of 10m.calculate the velocity with which the object was thrown upwards? Take g = 9.8 m/s2​

Answer 1

0 = 14 m s–1 – 9.8 m s–2 × t t = 1.43 s. Initial velocity, u = 14 m s–1, and Time taken, t = 1.43 s.

Answer 2

Answer:

about 14.1 m/s

Explanation:

v=

$\sqrt{2gh}$

v=√2×10×10=14.1 m/s
