Required Speed

You’re driving your pickup truck around a curve with a radius of 22 m . A box in the back of the truck is pressed up against the wall of the truck.

 

How fast must you drive so that the force of the wall on the box equals the weight of the box?

Known Variables:

radius (r): 22 m

gravity (g): 9.8

“Centrifugal force represents the effects of inertia that arise in connection with rotation and which are experienced as an outward force away from the center of rotation.”

Since its a truck moving around a circle, we assume that it would be centrifugal force.

Centrifugal force Fc = m x v2 / r
Weight  = mg
As required by the question
Fc = W
v2 /r = g
given radius r = 22 m
v2 /22 = 9.8

Solve for v
required speed
 v = √(22 * 9.8)

= 14.35 m/s

v=15 m/s

  1. My friend suggested I may in this way web site. This individual had been completely appropriate. This specific create in fact made our working day. You cannot imagine the best way so much occasion I had spent because of this data! Many thanks!

  2. Thank you another beneficial website. Where in addition could I am getting that kind of knowledge printed in a real ideal indicates? I’ve a challenge that we are right now working on, and i have been in the particular peek away pertaining to these data.

  3. Jon, I don’t have access to the CMS (we have a franchise site) can I just post the code on each page?
