if by 'you', you mean 'u' then u is the initial velocity v is the final velocity. you need to know the initial velocity in trajectory question (motion of an object through the air) to find height, acceleration, time etc.
Acceleration is the rate of change in velocity.
Where a = (v-u)/t a is acceleration, v is final velocity u is initial velocity t is time so, u=v-at
Rate of change of velocity is called acceleration. The mathematical link is: acceleration a=dv/dt where v is the velocity. It's a derivative of v with respect to time t.
acceleration a----->velocity=acceleration x time: v=a x t
Time equals velocity divided by acceleration. t=v/a
a=dv/dt a=acceleration v=velocity t=time.
a=dv/dt a=acceleration v=velocity t=time.
a=dv/dt a=acceleration v=velocity t=time.
Acceleration is the the fluctuation in velocity per unit time.to calculate the acceleration we need the formula : Acceleration = Velocity fluctuations / time taken or Acceleration = Final velocity - Initial velocity / time taken or a = v-u/t
a=dv/dt a=acceleration v=velocity t=time.
a=dv/dt a=acceleration v=velocity t=time.
a=dv/dt a=acceleration v=velocity t=time.
