A mass m=400g hangs from the rim of a wheel of radius r=15cm. When released from rest, the mass falls 2.0m in 6.5sec. Find the moment of inertia of the wheel

A car starts from rest and accelerates uniformly to a speed of 50km/h in 18s. If the wheels of the car are 70cm in diameter. Calculate; a.The final angular velocity of the wheels b.angular acceleration

two men are carrying a 12m uniform ladder on their shoulders. Man A is 1.0m from one end, and man B is 3.0m from the other end. If the beam has a mass of 200kg, determine the load supported by each man.

Sorry Orbital speed

Spermatozoa and Oocytes... I thnk it should be that..

The First is -7.901. Just this in the moment.

c) 46.244

b) 1283994.39504

and the 2) (B) is 0.5

(x*Q)/(4*pi*epsilon_0*((R)^2+(x)^2)^(3/2))

I'm Try a But the b is: ((sigma*x)/(2*epsilon_0))*(1/(sqrt(x^2+R_1^2))-1/(sqrt(x^2+R_2^2)))

2.0 E2 J convert 10 kg to Newtons 10 kg = 98.0665 Newtons W = F(d) W = 98.0665 (2) W = 196.133 W = 2.0 E2 J when rounded 27J W = F (d) W = 9.0N (3.0m) W = 27J Time doesn't matter here
