A pilot ejects from his stalled plane with an upward velocity of 17m/s and no horizontal velocity. Calculate his velocity at each time given. (Ignore air resistance for this part) t = 1.0s: ______________ t = 1.7344s: ________________ t = 2.0s: ______________ t = 3.46689s: _______________ t = 227s: ________________
Given that at vertical velocity,
and
there is no horizontal velocity
-------------
At
Use formula
Pilot is moving upwards and g is acting downwards, so put negative sign.
Since there is no horizontal velocity and horizontal acceleration
