The height of a projectile that has been launched upward can be determined by finding the sum of the product of onehalf of the object’s acceleration and t2, the product of the object’s initial velocity and t, and the object’s initial height, where t represents the number of seconds after the object has been launched. An object’s acceleration can be assumed to be 32 ft/s2, which is the acceleration due to gravity.
a. Why do you think the acceleration due to gravity is represented by a negative number?

Best ResponseYou've already chosen the best response.1if you let upwards be positive and down be negative, the acceleration of gravity is down, it opposes upward motion

Best ResponseYou've already chosen the best response.1it is arbitrary, you call up negative and the acceleration would be +
