## Homework Statement

Refer to Fig. 5-38 (see below). Let the mass of the block be 2.3 kg and the angle x be 20°. Find (a) the tension in the cord and (b) the normal force acting on the block. (c) If the cord is cut, find the magnitude of the block's acceleration.

## Homework Equations

F=ma (Newton's Second Law)

## The Attempt at a Solution

I got a and b by figuring out the equations T=F(g)sinx and F=F(g)cosx where F(g) is the force due to gravity. Part C is where I have the problem. I thought that because the rope was cut, the tension there would be 0 and thus the acceleration would be the tenstion
