A mass of 8 kg lies on a horizontal, frictionless floor. A force of 72 Newtons pushes to the left (negative x direction) with a force of 72 Newtons. Another force of unknown magnitude pushes the mass in a direction of 21.4 degrees above the positive x axis. The mass is originally at rest before these forces are applied and 2.4 seconds after the forces have been applied, the mass has moved to the left a distance of 11.1 meters. What is the magnitude of the unknown force in Newtons?
Please help me solve this problem =/
your use of the word "above"...is it operating against gravity, or is it still on the horizontal perpendicular to the x direction?
No it is not Operating against gravity. It is still on the horizontal
Keleigh are you a tutor?
at Bobpursley: No it's not Operating against gravity. It's still on the horizontal perpendicular to the x-direction.
