the engine of a truck produces an acceleration of 2 metre per second square if truck pull another truck of same mass find the acceleration of combination of trucks with engine of truck 1
Answers
whatever be the mass of the car the force applied
since F = m *a
we get F = m * 6 => m = F/6.
now if a block of mass 'm'. Therefore mass the engine has to pull = 2m
since force applied by engine is constant F =
(2m)*A (A is the new acceleration)
now we put value of m (F/6) in this equation
and we get F = 2(F/6)*A
on solving A = 3 m/s².
