Given, m = 500 kg, u = 5 m/s and t = 20 s. Resultant force, F = 500 – 200 = 300 N Acceleration, a = F/m = 300/500 = 0.6 m/s² by question of motion: v = u ...

The endoplasmic reticulum is an extensive, interconnected, membrane-bound network of tubes and sheets that provide a route for intracellular transport of material.

a = slope of graph = 10 – 0/4 – 0 = 2.5 m/s² F = ma = 5 x 2.5 = 12.5 N
