SITUATION 7. The acceleration of a particle is given by a = −k²s, where a is in meters per second squared, k is a
constant, and s is in meters. Determine the velocity of the particle as a function of its position s. Evaluate your
expression for s = 5m ifk = 0.1m-¹5-² and the initial conditions at time t = 0 are so = 3m and vo=10m/s.
SITUATION 8. A balls is thrown vertically up with a velocity of 30m/s at the edge of a 60m cliff. Calculate the
height h to which the ball rises and thee total time t after release for the ball to reach the bottom of the cliff. Neglect
air resistance and take the downward acceleration to be 9.82m/s².
