# Vector Math 101 Homework

Solutions to Monday Homework:For each force diagram, determine the net or resultant force (∑F), the mass and the acceleration of the object. Identifythe direction (the second blank) of the two vector quantities. NOTE: Fgravstands for the weight of the object.NOTE:In each problem below, the net force (∑F) is determined by adding up all the individual force valuesas vectors; theirdirection must be considered when adding them. The mass is the down force (Fgrav) divided by 9.8 N/kg; the reported mass valuesare rounded at the second digit. The acceleration is determined by dividing the net force (∑F) by the mass (unrounded value);reported values are rounded at the second digit.a.∑F =600 N,downm =61 kga =9.8 m/s2,downb.∑F =200 N,downm =61 kga =3.3 m/s2,downc.∑F =2000 N,leftm =820 kg (816 kg)a =2.5 m/s2,leftd.∑F =4000 N,leftm =820 kg (816 kg)a =4.9 m/s2,lefte.∑F =8 N,rightm =2.0 kg (2.04 kg)a =3.9 m/s2,rightf.∑F =16 N,rightm =4.1 kg (4.08 kg)a =3.9 m/s2,right

### Vector Introduction

A vector quantity has both magnitude and direction.

Problems involving velocities, displacements, forces and navigation are often made easier when vectors are used.
