Today, I was signed up for AP Physics. I have taken regular physics and it was easy. I am very very good at MATH. I can do math for hours for Fun. I have taken Alegbra 1 and Formal geomerty. I never got Less than A in math. Will I live through that class or not.

A small ball of mass 24 kg is suspended from a string of length 63 cm, and whirled in a circle lying in the horizonal plane. The acceleration of gravity is 9.8 m/s^2. If the string makes an angle of 36 with the vertical, find the centripetal force experience by the ball.

If we could travel at a faster pace than our universe is expanding, we would eventually catch up with it and overtake it (in millions of years). Now supposing we humans could live for enough years to do this, and we decided to chose a brave soul to experiment, what would happen when they caught up with the expansion of the universe and what would they travel into if they kept going? And how did the thing I would travel into actually get here??

A 50 N crate is pulled up a 5 m inclined plane by a worker at constant velocity. If the plane is inclined at an angle of 37 degree and there exists a constant force of 10 N between the crate and the surface, what is the force applied by the worker?

I think you would go:
F= -10 +50N-9.8 to get 30 N

am I right? please help! thanks

There are several Pre-defined Resistance in Multimeter and you can set your knob according to it.
If the knob is set at 200k ohm and you are measuring the Resistance and you are getting the reading as 150 then
How would one interpret the reading ,150 Ohm or 150,000 Ohm?

I would like a refresher in the basics of projectile motion for algebraic physics. I know theta and the initial velocity. I need to find the max hight reached and the disstance it travils before hiting the ground. I would like some help with just remebering the equations needed for projectile motion. Thanks.
