Kinematic equations Definition and 113 Threads

[SOLVED] Kinematic Equations This is the question. I have sat here and tried to figure out how to even start this problem for hours. I can't seem to get it through my head. If someone could help me set it up, I can figure out the rest I think. Thanks in Advance. Q. A car and a...

[SOLVED] Different values with rotational kinematic equations Hello everyone, I got two different values for final angular speed when I tried to use the third and fourth kinematic equations. I filled the template here with the problem with my attempts. Homework Statement A bicycle wheel of...

Homework Statement For this project, we had to build a vehicle that would hold an egg, and drop it a distance of about 40 feet, and making sure the egg wouldn't break. There are various parts to the report part of this project, and I had a question about the first part. Basically, one part...

Homework Statement A 1.0kg wood block is launched up a wooden ramp that is inclined at a 38 degree angle. The block's initial speed is 14 m/s. (Use uk = .20 for the coefficient of kinetic friction for wood on wood.) a.) What vertical height does the block reach above its starting point...

hello, i'm having trouble with kinematic equations. i feel that i understand them, but when i get to a problem, I'm so confused. i can figure out what i have and what i don't have, but it's choosing the correct formula that is my main problem. how do i know when to solve for what...

Can they be used if the acceleration is = to zero?? I know that they can only be used if the acceleration is constant but is zero considered a constant?? Thanks =):confused:

Homework Statement After falling from rest a a height of 30 m, a 0.50 kg ball rebounds upward, reaching a height of 20 m. If the contact between ball and ground lasted 2.0 ms, what average force was exerted on the ball? Homework Equations The Attempt at a Solution I figured I had to...

A wheel 60.0 cm in diameter accelerates uniformly from 245 rpm to 395 rpm in 7.5 s. How far will a point on the edge of the wheel have traveled in this time? I keep getting 125.66, I don't really understand what forumal to use.

Hi, I'm new to this forum. I need major help on my homework. So the kinematic equation, Vf² = Vi² + 2ad I need to figure out how to manipulate it so I can find Vf(final velocity), Vi(initial velocity), a(acceleration), and d(displacement). I figured to find Vf, you just square root it...

Im a 1st year physics student in the 11th grade. I haven't had much trouble with the assignment, but for some reason i cannot get the correct solution on this problem. A certain car is capable of accelerating at a rate of 0.57 m/s2. How long does it take for this car to go from a speed of 53...

This is a problem that appeared quite simple but is for some reason incorrect. I am not quite sure where I made my mistake so I spelled out my thought process below: Question: "Suppose that a cart was released from rest at a position of 3.5 cm down the ramp and continued to travel down the...

I'm a little confuse about these. velocity as a function of time, displacement as a function of time and velocity as a function of displacement. I know how to use this formulas, but in my lab there is a question that I am stuck on. How are this kinematic equations related to each other? and...

Since a good amount of the posts refer to problems involving kinematics I figured this may be helpful V_0 = Inital Velocity V = Final Velocity t= time a= acceleration x= distance x=V_0t+\frac{1}{2}at^2 V=V_0+at V^2=V_0^2+2ax x= \frac{1}{2}(V_0+V)*t
