Force On An Object#

The velocity as a function of time of an object is as shown in the figure below. The mass of the object is 20 \(kg\).

A graph of velocity and time. The object has a velocity of 10 meters per second at 0 to 2 seconds. The object's velocity decreases to 0 meters per second at 6 seconds. The object's velocity is at negative 10 meters per seconds from 10 to 12 seconds.

Part 1#

Which answer below best describes the force on the object between 2 and 10 \(s\)?

Answer Section#

  • \(F = \) -50.0 \(N\)

  • \(F = \) 50.0 \(N\)

  • \(F = \) 50.0 \(N\) from 2 to 6 \(s\), then \(F = \) -50.0 \(N\) from 6 to 10 \(s\)

  • \(F = \) -50.0 \(N\) from 2 to 6 \(s\), then \(F = \) 50.0 \(N\) from 6 to 10 \(s\)

  • Impossible to tell
