Question

An object is thrown vertically upwards from the ground with a velocity of 5ms
i) What is its velocity at its maximum height?
ii) State the type of velocity possessed by the object.
iii) What is the velocity with which it will hit the ground?​

Answer 1

Answer:

Distance travelled, s = 10 m

Final velocity, v = 0 m/s

g = -9.8 m/s

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
