There are actually 2 questions that i have(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

First is

a frictionless pulley with zero mass is attached to the ceiling, in a gravity field of 9.80 m/s2. Mass M2=0.250 kg is being accelerated downward with a=1.40m/s2. calculate the mass m1.

Second is

A small steel ball bearing with a mass of 24.0g is on a short compressed spring. when aimed vertically released, the spring sends the bearing to a height of 1.27m. calculate the horizontal distance the ball would travel if the same spring were aimed 35.0 deg from the horizontal

2. Relevant equations

so not so much wanting the answer just the equations on how to do these so then i can figure it out myself. thanks

3. The attempt at a solution
