The drawing shows three objects rotating about a vertical axis. The mass of each object is given in terms of m0, and its perpend

photoshop1234 [79]

Answer:

I₁ > I₃ > I₂

Explanation:

Taking the pic shown, we have

m₁ = 10m₀

m₂ = 2m₀

m₃ = m₀

r₁ = r₀

r₂ = 2r₀

r₃ = 3r₀

We apply the formula

I = mr²

then

I₁ = m₁r₁² = (10m₀)(r₀)² = 10m₀r₀²

I₂ = m₂r₂² = (2m₀)(2r₀)² = 8m₀r₀²

I₃ = m₃r₃² = (m₀)(3r₀)² = 9m₀r₀²

finally we have

I₁ > I₃ > I₂

A soccer ball kicked with a force of 12.5 N accelerates at 6.2 m/s’ to the right. What is the mass of the ball? Answer in units

stepladder [879]

Answer:

m = 2.01[kg]

Explanation:

This problem can be solved using Newton's second law which tells us that the force applied on a body is equal to the product of mass by acceleration.

$F =m*a$

where:

F = force = 12.5 [N]

m = mass [kg]

a = acceleration = 6.2 [m/s²]

$12.5=m*6.2\\m = 2.01[kg]$

A small sphere is hung by a string from the ceiling of a van. When the van is stationary, the sphere hangs vertically. However,

olganol [36]

Answer with Explanation:

We are given that

String makes an angle w.r.t vertical= $\theta=$

a.We have to derive an expression for the magnitude of the acceleration of the van in terms of the angle $\theta$ and magnitude g of the acceleration due to gravity.

According to newton's second law

$T sin\theta=ma$

$Tcos\theta=mg$

$\frac{Tsin\theta}{Tcos\theta}=\frac{ma}{mg}$

$tan\theta=\frac{a}{g}$

$a=gtan\theta$

b. $\theta=10^{\circ}$

$g=9.8 m/s^2$

$a=9.8\times tan10^{\circ}=1.73 m/s^2$

c.Velocity=Constant

We have to find the angle $\theta$

$a=0$

$0=9.8tan\theta$

$tan\theta=0$

$tan\theta=tan0$

$\theta=0^{\circ}$
