PHY2048 Unit 1 Assignment Show all your steps and draw diagrams where necessary. 1. A missile is aimed to hit a target 650 km away. If the missile is fired at an angle of 20 o with the horizontal, what should be its launch speed so that it will hit the target? Once fired, how long does the missile take to hit the target? 2. When a particle is at the origin, it has a velocity given by v o = (12 i + 15 j )ms -1 . It has a constant acceleration given by a = (-1.5 i + 0.25 j ) ms -2 . (a) How long does it take the particle to hit the y-axis? (b) At what point does it hit the y-axis? (c) What is its velocity at the instant it hits the y-axis?
