## Homework Statement

A box of mass M=10 kg is at rest on a frictionless level surface (like an ideally smooth ice

rink). A rope tied to the box is pulled horizontally, such that the tension in the rope is

T = 75 ˆx + 25 ˆz N, where both the x-axis and the z-axis are parallel to the floor. What is the speed of the box after 0.05 seconds?

## Homework Equations

Magnitude of T = (75^2 + 25^2)^(1/2) = 79 N

weight of box = 10 kg * 9.8 m/s^2 = 98 N

## The Attempt at a Solution

Because the weight of the box is greater than the tension force, the box should not move, right?
