an object 5 s to reach the Grond from a height of 5m on a planet what is the value of g on the planet |
|
Answer» Formula to be used : Second EQUATION of motion S = UT + 1 / 2 gt² S refers to height, U refers to initial velocity, t refers to time and g refers to gravity. S = 5 m ; t = 5 seconds ; U = 0 m / s ( As OBJECT is dropped from rest ) Substituting in the equation we get, 5 m = 0 * 5 + 1 / 2 * g * 5² 5 m = 0 + 25 / 2 * g 5 m = 25 * g / 2 => 5 m * 2 / 25 = g => 10 m / 25 second² = g => g = 0.4 m/s² |
