A 40.0 kg wagon is towed up a hill inclined at 17.9° with respect to the horizontal. The tow rope is parallel to the incline and has a tension of 140 N. Assume that the wagon starts from rest at the bottom of the hill, and neglect friction. How fast is th...

A box of books weighing 280 N is shoved across the floor of an apartment by a force of 390 N exerted downward at an angle of 35.1° below the horizontal. If the coefficient of kinetic friction between box and floor is 0.57, how long does it take to move th...

Rather than promoting goods and manufactures, the 1939 New York World's Fair sought to emphasize

In his 1992 speech, how did Mikhail Gorbachev view the impact of the global communications revolution on the people of less-developed countries?

Starting from rest, a disk rotates about its central axis with constant angular acceleration. In 4.0 s, it has rotated 30 rad. Assuming that the acceleration does not change, through what additional angle will the disk turn during the next 7.0 s? I calcul...

so, (3.75)(4) + (.5)(3.75)(49) or 106.875 radians that's not the correct answer, so is it just the second part to find the additional angle? (.5)(3.75)(49) = 91.875 but it too is incorrect, what am I missing?

Why did Arabic numerals replace Roman numerals?

Name two metals that do not always lose the same number of electrons when they form ionic bonds. How can you tell? plss help TwT

what about part 2 ?

so, (3.75)(4) + (.5)(3.75)(49) or 106.875? or just the second part to find the additional angle? (.5)(3.75)(49) = 91.875 but it is incorrect, what am I missing?

The angular velocity after 4s is 15r/s so would it be 15(7) + .5(3.75)(49) = 196.875?

It is! Thanks for your help

you guys are legit no help lmfaoooooooooooooooooooooooooooooooooooooooooooooooo

all correctttt
