m=dv
m=dv
Mass = density x volume M=DV hi this means mass equals density multiplied by volume. so mass=d times v
Density , "m/v=d and m=dv "
126km/h /3.6 = 35 m/s deceleration equals a = v2/ 2s 352 / (2 x 200) = 3.0625 m/s2 a = dV/dT rearranged dT = dV/a 35/ 3.0625 = 11.43 seconds
Force (F) F = m.a and since a = dv/dt thus F = m.dv/dt Momentum (p) p = m.v and since a = dv/dt thus p = m.a.dt By switch dt from R.H.S. to L.H.S we get dp/dt = m.a thus F = dp/dt
viscous force F=uA(dv/dr) u=(constant) Dynamic viscosity A=area dv/dr=Velocity gradient
The condition for maximum velocity is acceleration equals zero; dv/dt = a= o.
