Given: Initial velocity
Final Velocity
To find : Height when jumpled 8.0 m/s upwards.
Solution: We already have values of initial velocity and final velocity.
We know, accereration due to gravity is given by .
It's negative because when jump it's in opposite direction.
Where h is the height when jumpled 8.0 m/s upwards.
Plugging values of
64= 225 -19.6h
Subtracting both sides by 225.
64-225= 225 -19.6h-225.
We get,
-161 = -19.6h
Dividing both sides by -19.6, we get
h= 8.2143
Rounding to nearest tenth, we get
h= 8.2 meter.
His height is 8.2 meter when he is jumping 8.0 m/s upwards.
