A student with mass 55 kg jumps off a high diving board.
Using 6.0×10^24 kg for the mass of the earth, what is the acceleration of the earth toward her as she accelerates toward the earth with an acceleration of 9.8 m/s2 ? Assume that the net force on the earth is the force of gravity she exerts on it.
F = 6.0x10^24 kg x 9.8 m/s^2
F = 5.88x10^25 N
5.88x10^25 N = 55 kg * a
a = 1.07 x^24 m/s^2
1 answer
The acceleration of the earth toward the student is 1.07 x 10^24 m/s^2.
