From newton's first law, an object remains in its inertial frame until a force acts upon it. This means that according to a stationary observer, the object will remain at rest or continue moving at the...
For any question which asks you to consider multiple forces acting on a body, the first thing you should do is draw a clear diagram, with all forces (and in this case angles) labelled.Once this has been d...
To answer this question, all you have to know is that the amount of material as a function of time, M(t), is related to the decay constant, λ, by the equation
M(t) = M0exp(-tλ)...
By just a quick look you might be tempted to say 30 m. However the key information is that the breaking force is the same. We can calculate the deceleration of the car when at 10m/s using the equation ...
Here, we must consider our UVAST equations of motion, and our variables.
U=?ms^(-1), V=45ms^(-1) , A=?ms^(-2), S= 300m, T=10s
Our equations of motion are:
