4. Determine V,-V2 + V3 from the previous exercise 5. The position of a particle as a function of time is given by the equation F = (9.60tT+8.85)1.00t2k)m. Determine the velocity and acceleration of the particle as a function of time. 6. A diver runs at 2.3 mls and dives horizontally from the edge of a vertical cliff and hits the water 3.0 3 later. How high is the cliff and how far from the base of the cliff does the diver hit the water? 7. A ball thrown horizontally at 23.7 mls from the roof of a building falls 31.0 m from the base of the building. How tall is the building? 8. A projectile is fired from the edge of a cliff, which is 115 m above the level from the ground, with an initial speed of 65.0 mls at an angle of 35.0\" above the horizontal, as shown in Figure 344. to. Determine the time it takes for the projectile to reach point P at ground level. b. Determine the horizontal distance X from point P to the base of the cliff At the instant just before the projectile reaches point P, find 0. the horizontal and vertical components of its velocity, d. the magnitude of the speed, and. the angle formed by the velocity vector with the horizontal. F. Determine the maximum height, above the top of the cliff, that hits the projectile. 1)\": hit] 1118
