A student of mass 45 kg jumps off a high diving board. What is the acceleration of the earth toward her as she accelerates toward the earth with an acceleration of 9.8 m/s? Use 6.0 X 1024 kg for the mass of the earth, and assume that the net force on the earth is the force of gravity she exerts on it.

Solution 25E Step1 : In this question, we need to find the acceleration exerted by earth on a student Let us consider the data given Mass of student m = s5 kg Acceleration of student on earth a = 9.8 m/s 2 e 24 Mass of earth m =e6.0 × 10 kg Step 2 : We shall use Newton's third law of motion to solve this Which say every object exerts equal and opposite force on another object That is F = F ---------(1) 1 2
