Hey guys, I'm not great at physics and my brain sometimes just doesn't get the sort of "implied" aspects of a problem. So I could use some help with an easy question.
In projectile motion, there are certain constants given particular circumstances, right?
I have to find the height of a...
A car which is originally at rest accelerates down a road with a net force of 32000 N acting on a 1980 kg car. At t = 12 seconds the driver slams on the brakes to avoid hitting a deer. Calculate the distance traveled by the car.
Coefficient of kinetic friction for the rubber on pavement is...
Need help calculating friction and normal force for "Measuring Friction" Lab
Hey guys, I'm not great at physics and have a lot of work ahead of me so I could use some help.
The lab setup is a wooden block sliding on a wooden surface. There is a weight attached to the block by a string that's...

There's my fbd and hopefully correct components, sorry its small.
So does the weight of the lamp have to be equal to the y component and the chain equal to the x component but in the negative direction?
If I seem slow it's because this is my...
I've done a free body diagram. I am still confused as to how to find the weight of the lamp. Does the combined force of the chain and the pull of the lamp have to equal 110 N?

Okay, so I was given a diagram that looks like the one I linked to above.
This is pretty basic, using Newton's second law to find-
A) the weight of the "lamp"
B) the tension in the chain
The strut is exerting a...
