If gravity is the only acceleration affecting the object, what is gravity’s constant value (include units in your answer)?-9.2 * 4.9 = 9.8-d = -9.......
An object in free fall has its distance from the ground measured by the function d(t) = –4.9t 2 + 50, where d is in meters and t is in seconds. If gravity is the only acceleration affecting the object, what is gravity’s constant value (include units in your answer)?
-
9.8 m's^2
Because d = (1/2) * a * t^2
2 * 4.9 = 9.8
-
d'' = -9.8 m/sec^2
