A cannon ball is fired with an initial speed of 123 m/s at angle of 60 degrees from the horizontal. Express the initial velocity as a linear combination of its unit vector components. Do not round off answers. V0 + (___________ m/s) i + ( ____________ m/s) j At the maximum height, the speed of the cannon ball is v = _______ m/s and the magnitude of its acceleration is a = ________________ m/s2. The time needed to reach maximum height is t = _______ s. The maximum height reached by the cannon ball is H = ______ m.
Supply all missing information with the correct numerical values. Do not include the units. Round off all answers to two decimal places. Do not forget the negative sign (-) if needed.
