Aperson is pushing a wheelbarrow along a ramp that makes an angle α = 33.0° with the horizontal. the wheelbarrow and load have a combined mass of 23.65 kg with the center of mass at the midpoint of the length l. what is the total force the person must apply so that the wheelbarrow remains horizontal on that ramp?

Explanation:

Since the wheelbarrow is maintained at horizontal position

so we can use Torque balance equation

Now force balance in Y direction we have

Now force balance in x direction we have

Now net force exerted by the person

a, c, d, e are all applying about success strategies.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
