1
Q
how is the modelling assumption that the string is light and inextensible been used
A
because it is inextensible, acceleration will be the same for both particles
2
Q
what is the equation for friction
A
F = μR
3
Q
what does suvat mean
A
s - displacement
u - initial velocity
v - final velocity
a - acceleration
t - time
4
Q
what is newtons second law
A
f = ma
every action has an equal and opposite reaction
5
Q
what is a resultant force
A
overall force acting on the object will accelerate in the direction of rf
