A car travels along a straight line at a constant speed of 56.0 mi/h for a distance d and then another distance d in the same di

rection at another constant speed. The average velocity for the entire trip is 33.5 mi/h. (a) What is the constant speed with which the car moved during the second distance d?
I started out with Vxavg=(Vxi+Vxf)/2 and came out to 11 and it was wrong. If anyone has a good website I can use to learn physics it would be much appreciated.

2* v1 * v2 / (v2+v1) = V avg2*56* v2 / (v2+56) = 33.5
v2 = 23.94 m/s

The mechanical advantage of the forklift is calculated to be 4.

<h3>MECHANICAL ADVANTAGE:</h3>
  • The mechanical advantage of a machine can be calculated by dividing the load (F) by effort (F). That is;

M.A = Load/Effort

  • According to this question, a crate required 900 newtons (N) of force to lift. The crate was lifted by a forklift with an engine that provided 225 N of force. The mechanical advantage is calculated as follows:

M.A = 900N ÷ 225N

M.A = 4.

Therefore, the mechanical advantage of the forklift is calculated to be 4.
