Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required =
time required =
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
A ammeter. I hope this helps.
PART a)
Force of friction on the box is given by formula
now the component of weight along the inclined
now by force balance the force required to hold the block
Part b)
to slide the block upwards the friction force will be upwards along the plane
Part c)
Kinetic friction on the block is given by
now in order to move it up
Part d)
now to accelerate upwards by 0.65 m/s^2 we can use
So the equation ask to calculate on how much can you lift using 1.4m long wheelbarrow that weighs 80n with its CG.5m from the center of the wheel and the weight will be 1740N. I hope you are satisfied with my answer and feel free to ask for more.
