Question

an object of mass 6000 kg rests on the flatbed of a truck. it is held in place by metal brackets that can exert a maximum horizontal force of 9000 N. when the truck is traveling 15 m/s, what is the minimum stopping distance if the load is not to slide forward into the cab?

Answer 1

minimum stopping distance will be d = 75 m

Step-by-step explanation:

Maximum force exerted by the bracket is given as

F = 9000 N

now we know that mass of the object is

m = 6000 kg

so the maximum acceleration that truck can have is given as

`F = ma`

`9000 = 6000 a`

`a = 1.5 m/s^2`

now for finding minimum stopping distance of the truck

`v_f^2 - v_i^2 = 2a d`

`0^2 - 15^2 = 2(-1.5) d`

`d = 75 m`
