What is the gravitational force of attraction between a planet and a 17-kilogram mass that is freely falling toward the surface of the planet at 8.8 m/s2?
a. 1.9 N
b. 8.8 N
c. 0.52 N
d. 150 N
The gravitational force of attraction between two objects can be calculated using the formula F = mg, where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity. In this case, the mass of the object is 17 kilograms and the acceleration due to gravity is 8.8 m/s².
Plugging these values into the formula, we get F = (17 kg)(8.8 m/s²) = 149.6 N.
Therefore, the correct answer is d. 150 N.
