5. Solve the following examples.a. An object takes 5 s to reach theground from a height of 5 m on aplanet. What is the value of g on theplanet?Ans: 0.4 m/s2b. The radius of planet A is half theradius of planet B. If the mass of A isM., what must be the mass of B sothat the value of g on B is half that ofits value on A?Ans: 2Mc. The mass and weight of an object onearth are 5 kg and 49 N respectively.What will be their values on themoon? Assume that the accelerationdue to gravity on the moon is 1/6thof that on the earth.Ans: 5 kg and 8.17 Nin step by step method |
