Write the equation of motion when a body starts from rest and body moves with uniform retardation |
|
Answer» If a body starts from rest and moves with uniform acceleration, then the displacement of the body is DIRECTLY proportional to the CUBE of the TIME.Explanation:Initial VELOCITY of the body U = 0 Let the constant acceleration be a. S = ut + 1/2 * a * t ^ 2 Displacement of the body S = ut + S = 0 + 1/2 * a * t ^ 2 S = (a * t ^ 2)/2 We get S = Thus, displacement of the body is directly proportional to the square of the time. |
