A van traveling at a speed of 32.0 mi/h needs a minimum of 42.0 ft to stop. If the same van is traveling 67.0 mi/h, determine it

makkiz [27]

Answer:

Δx= 184.12 ft

Step-by-step explanation:

The equation you need to use is velocity as a function of displacement.

$v^2= u^2 +2a(\delta x)$

v = the speed at which the car is travelling,

and

v_o is the original speed (in this case zero).

The change in x (displacement) is how far the car travels. You will be solving for a (acceleration).

$32^2= 0^2+ 2a\times42$

solving we get

a= 12.19

now put this acceleration value into the second case when v= 67mi/h

$67^2= 0^2 + 2\times12.19(change in x)$

⇒Δx= 184.12 ft
