To find the time it takes for the object to reach its maximum height, we need to use the formula t = v/ g, where v is the initial velocity and g is the acceleration due to gravity. Since the object is thrown upwards, we take g to be negative (-9.8 m/s^2). Therefore, t = 14.0 / 9.8 = 1.43 s (rounded to two decimal places).
