What is its speed after 3. 83 as if it accelerates uniformly at −3. 04 m/s 2 ? answer in units of m/s.
weeeeeb [17]

The velocity equation is v_{final} =v_{initial} +at\\

Known facts:

  • t = 3.83s
  • a= -3.04
  • intial velocity = 0

Plug into equation known quantities:

   v_{final} = (-3.04) * 3.83 = -11.6432m/s

Thus the final velocity is -11.6432m/s

Hope that helps!

The cylindrical head bolts on a car are to be tightened with a torque of 63.3 N · m. If a mechanic uses a wrench of length 18.2
Nataly_w [17]

Answer: The perpendicular force to be used to tighten the bolt is

F=347.8N

Explanation:

Mathematically the torque is expressed as

T=F*L

Where T= torque in Nm

F= force in N

And L = perpendicular distance

Now given

T=63.3Nm

L=18.2cm to meter 18.2/100

0.182m

F=?

Making F the subject of the formula in our equation

F=T/L

F=63.3/0.182

F=347.8N

What is torque?

Torque is the product of force and perpendicular distance of the line of action.

There is a basketball with a diameter of 9in. and a softball with a diameter of 4in. Find how many times greater the volume of t
erica [24]

Answer: #.37 times greater

Explanation: Volume of a sphere is: V = \frac{4}{3}·π·r³

Since it is given the diameter of the basketball and the softball, their ratios are r₁ = 3in and r₂ = 2in, in which index 1 represents the basketball and index 2, the softball.

Calculating the volume of basketball:

V₁ = \frac{4}{3} . 3.14 . 3³

V₁ = 113.04 in³

Calculating the volume of softball:

V₂ = \frac{4}{3} . 3.14 . 2³

V₂ = 33.5 in³

Comparing one volume with the other:

\frac{V1}{V2} = \frac{113.04}{33.5} = 3.37

We have that V₁ = 3.37V₂

This means the volume of a basketball is 3.37 times greater than the volume of a softball.
