No we do not have velocity as a function of time, we have it as a function of space. Therefore we can't just differentiate and get the accel.

Homework Statement The speed of a particle of mass m varies with space as v(x) =ax^-n v(x=0)=0 at t=0. Find F(x).Homework Equations F=ma=m dv/dt The Attempt at a Solution I am not really sure where to start from. Would x(t) or f(t) be relevant?

Why is it not possible for a particle to be neither symmetric nor antisymetric on exchange? If a particle can have 1/2 integer spin why can't it have 1/3 , 1/4 etc. I know it's a weird question to ask but I've been wondering about it for a while.

This is a question about inertial frame of reference. The ball is not moving horizontally when you throw it up, relative to you. It is moving relative to the ground int the same direction and at the same speed as everyone and everything else on the bus is. If an outside observer were to watch...

Homework Statement In a tug of war, five men on each team pull with an average force of 500 N each. What is the tension in the center of the rope. A. zero B. 100N C. 500N D. 2500N E.5000N Homework Equations The Attempt at a Solution I know this isn't a very complicated...

Homework Statement A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 720-kg helicopter rises from rest to a speed of 7.5 m/s in a time of 5.0 s. During this time it climbs to a height of 7.9 m...
