If v = (4t+5) m/s, where t is in seconds, determine a when t = 2 s. 2. If s = (2t³) m, where t is in seconds, determine v when t = 2 s. 3. If a = 2 m/s², determine v at s = 4 m if v = 3 m/s at s = 0. 4. If a = 4 m/s², determines when t = 3 s if v = 2 m/s and s = 2 m when t=0. 5. A particle moves along a straight line such that its position is defined by s = (t² - 6t + 5) m. Determine the average velocity, the average speed, and the acceleration of the particle when t = 6 s. 6. A particle is moving with a velocity of vo when s=0 and t=0. If it is subjected to a deceleration of a = -kv³ where k is a constant, determine its velocity and position as functions of time. 7. A particle travels along a straight-line path such that in 4s it moves from an initial position SA = -8 m to a position SB = +3 m. Then in another 5 s it moves from SB to sc = -6 m. Determine the particle's average velocity and average speed during the 9-s time interval. 8. The acceleration of a rocket traveling upward is given by a = (6+0.02s) m/s² where s is in meters. Determine the time needed for the rocket to reach an altitude of s = 100 m. Initially, v = 0 and s=0 when t=0. 9. Draw the s-t and a-t graphs if s=0 when t=0 v (m/s) 4 v = 21 2 t(s)
