Question

An object is thrown vertically, up was ds and vises to a height of 1°m. Calculate (1) The vebcity with which the object was thrown upwards and (i) the time taken by the object to reach the highest pointe​

Answer 1

Answer:

1.43 second is answer

please mark me brainliest

Explanation:

Distance travelled, s = 10 m

Final velocity, v = 0 m/s

g = -9.8 m/s

2

1) Using,

v

2

−u

2

=2gs

u

2

=196

u=14m/s, where u is the velocity with which the object is thrown upwards.

2) Using,

v=u+gt

t=

g

v−u

=1.43 sec
