A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 138 feet per second from an initial height of 139 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation: h=-16t + 138t + 139 Find the two points in time when the object is 170 feet above the ground. Round your answers to the nearest hundredth of a second (two decimal places). Enter your two answers separated by a comma.

A cart starting from rest at a height of 1.00 m above a tabletop can roll down two different ramps—one that goes in a straight line from A to B at a 15º incline, and one that descends at a 30º incline from A and is then level until B. Calculate the time it takes for the car to get from A to B along each ramp. The answers are 1.74 s and 1.35 s. I need help on some of the steps
