Question

1. a student pulls a 60 - newton sled with a force having a magnitude of 20. newtons. what is the magnitude of the force that the sled exerts on the student? (1) 20. n (2) 40. n (3) 60. n (4) 80. n 9. the data table below lists the mass and speed of four different objects. data table which object has the greatest inertia? (1) a (2) b (3) c (4) d 10.

Explanation:

Step1: Recall the concept of inertia

Inertia is a property of matter that depends on mass. The greater the mass of an object, the greater its inertia.

Step2: Compare the masses of the objects

Object A has a mass of \(4.0\space kg\), object B has a mass of \(6.0\space kg\), object C has a mass of \(8.0\space kg\), and object D has a mass of \(16.0\space kg\).
Since \(16.0>8.0 > 6.0>4.0\)

Answer:

(4) D
