A rocket is launched at an angle of 54.0° above thehorizontal with an initial speed of 97m/s. The rocket moves for 3.00 s along its initial line of motionwith an acceleration of 30.0m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile.
(a) Find the maximum altitude reached by the rocket.(b) Find its total time of flight.(c) Find its horizontal range.
A concave mirror forms a real image twice as large as the object. The object is then moved such that the new real image produced is three times the size of the object. If the image was moved 62.5 cm from its initial position, how far was the objec..
