An athlete at the gym holds a 3.0 kg steel ball in his hand. His arm is 78 cm long and has a mass of 3.8 kg, with the center of
Elina [12.6K]

Answer:

a. 34.6 Nm

b.24.4 Nm

Explanation:

a.

78 cm = 0.78 m

W = F =mg

m1 = mass of steel ball = 3 kg

m2 = mass of long arm = 3.8 kg

moment due to steel ball = Fd =(m1*g)*(0.78)= (3*9.81)(0.78)=22.95 = 23 Nm

moment due to arm =Fd=(m2*g)*(0.78*0.4)= (3.8*9.81)(0.312)=11.63 = 11.6 Nm

net moment = 23 +11.6 = 34.6 Nm

b. now in this the angle will change the perpendicular moment arm

   moment due to steel ball = (3*9.81)*(0.78cos45) = 16.23 =16.2 Nm

   moment due to arm = (3.8*9.81)(0.4*0.78cos45) = 8.22 = 8.2 Nm

net moment = 16.2 +8.2 = 24.4Nm

If a 4500 kg car is traveling with an acceleration of 35.2 m/s/s, what is the force acting on it?
Elena L [17]

Answer:

<h2>158,400 J</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 4500 × 35.2 = 158400

We have the final answer as

<h3>158,400 J</h3>

Hope this helps you

Match the measurements with the proper SI unit.
Ivan

Answer:

Acceleration:

C. Meters per second squared

Velocity:

B. Meters per second

Distance:

A. Meters

Explanation:

We must remember that the international system of measures (SI) takes into account for the length as the main unit the meter, for the mass the kilogram, for the time the second.

The acceleration is calculated using the following expression

a = v/t = (m/s/s) = (m/s^2]

The velocity is calculated using the following expression

v = x/t = (m)/(s) = (m/s)

The distance for the SI system is given in meters
