Question

on earth, an object that has a mass of 75 kg. on the moon, where the acceleration of gravity is 1.66 m/s, the same object would have a weight of _ newtons. 0 n, its weightless because theres no gravity 735 n 75 n 124.5 n question 2 10 pts on the surface of the earth, all objects fall with a constant acceleration speed velocity trajectory

Explanation:

Step1: Recall the formula for weight

Weight \(W = m\times g\), where \(m\) is mass and \(g\) is acceleration due to gravity.

Step2: Substitute the given values

Given \(m = 75\space kg\) and \(g=1.66\space m/s^{2}\). Then \(W=75\times1.66\).

(Question 2):
On the surface of the Earth, according to the law of free - fall (neglecting air resistance), all objects fall with a constant acceleration. The acceleration due to gravity \(g\approx9.8\space m/s^{2}\) near the Earth's surface. Speed and velocity are not constant (they change as \(v = v_0+gt\) for initial velocity \(v_0 = 0\), \(v=gt\)). The trajectory is a parabolic path (for projectile motion, but for free - fall (vertical motion) it's a straight - line).

Answer:

124.5 N
