Question

3. An bull is thrown Vestically
thrown Vertically upwards and
rises
height of to 10
m. Calculate:
ci) the volocity with which the object was
thrown upwards ?
(2) time taken by the object to reach
the highest point?

​

Answer 1

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

hope you understand it ........
