I know this isn't a site to post physics help lol but i have a test tomorrow and i need help :/

if you can answer thanks


a child pulls a 34kg wagon a distance of 12.0m with a force of 33N at an angle of 25 degrees to the horizontal. Assuming friction is negligible and the wagon starts from rest, determine the acceleration and final speed of the wagon.

Okay, so first off lets determine your acceleration with Newton's 2nd Law.

1.)
F = ma
a = F / m
= 33.0N / 34kg
= .9705m/s^2

The wagons final speed by kinematics is:

2.)
vf^2 = vi^2 + 2ad
v = (Take square root of following # last)[(0.0m/s) + 2(.9705m/s)(12.0m)]
= 4.826m/s

Vf being final velocity
Vi being intial velocity
A being acceleration
And D being displacement
