Question

An onion crate with a weight of 225 N accelerates along a frictionless surface as the crate is pulled with a force of 14.5 N as shown in the drawing. What is the horizontal acceleration of the crate?

Answer 1

$$m=\frac{W}{g}\\ma=F\cos{19}\\\frac{W}{g}a=F\cos{19}\\\frac{225}{9.8}a=14.5\cos{19}\\a=0.597\frac{m}{s^2}$$
