"A Phy 201 6-10 H N 64 × a heavy load, such as steel beams. A the cab, if the truck stops saddenly in an braking. Assume, for example, that a 12.000 kg load sits on the flat bed of a 25,000 ko trock the flat bed of the truck. moving at 13.0 my's. Assume that the load is not ted doen to the truck, but has a coefficent of friction of o.s00 with (a) Cakculate the minimusm stopping distance for the truck for which the load will not slide forward relative to the trck m (b) Is any piece of data unnecessiry for the solution?

Explanation / Answer

Given,

m = 12000 kg ; M = 25000 ; v = 13 m/s ; u = 0.5

(a)We know that frictional force is:

Ff = u mg = ma

a = ug = 0.5 x 9.81 = 4.91 m/s^2

from eqn of motion

v^2 = u^2 + 2 a S

S = (v^2 - u^2)/2a

S = (0^2 - 13^2)/2 x -4.91 = 17.21 m

Hence, S = 17.21 m

b)Mass of truck
