Temperature IS heat energy. They are the same exact thing.
By definition of average acceleration,
<em>a</em> = (20 m/s - 33.1 m/s) / (4.7 s) ≈ -2.78 m/s²
Vertically, the car is in equilibrium, so the net force is equal to the friction force in the direction opposite the car's motion:
∑ <em>F</em> = (1502.7 kg) (-2.78 m/s²) ≈ -4188.38 N ≈ -4200 N
If you just want the magnitude, drop the negative sign.
Answer:
The average velocity would be 217 m/s.
Explanation:
Average velocity is calculated by v(avg)=final velocity+inital velocity over 2
Displacement is the change in position (vector)
Velocity is calculated by s= d/t distance/time
The tension in the string supporting the rod and the attached weights is 7.11 N.
<h3>Tension in the string supporting the rod</h3>
The tension in the string supporting the rod and the attached weights is the sum of the weights supported by the strings.
T = (m1 + m2)g
where;
- m1 and m2 are the two masses supported
0.4lb + 1.2lb = 1.6lb = 0.725 kg
T = 0.725 x 9.8
T = 7.11 N
