An object on a planet has a mass of 243 kg. What is the acceleration of the object, if the radius of the planet is 2.32 x 10^7 m , and the mass of planet is 6035 x 10^30 kg? Estimate G as 6067 x 10^-11 N (m/kg)^2

The acceleration of the object is 7.87 x 10⁵ m/s²

Explanation:

Given;

mass of the object, m = 243 kg

mass of the planet, M = 6.35 x 10³⁰ kg

radius of the planet, R = 2.32 x 10⁷ m

universal gravitation constant, G = 6.67 x 10⁻¹¹ Nm/kg²

Apply Newton's second law of motion and Newton's gravitational law;

Therefore, the acceleration of the object is 7.87 x 10⁵ m/s²

that would be because of both gravity and friction. so     c

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
