I believe it’s power, but i could be wrong!
In general, the quantity of heat energy, Q, required to raise a mass m kg of a substance with a specific heat capacity of <span>c </span>J/(kg °C), from temperature t1 °C to t2 °C is given by:
<span>Q </span>= <span>mc(t</span><span>2 </span><span>– t</span>1<span>) joules</span>
<span>So:</span>
(t2-t1) =Q / mc
<span>As we know:
Q = 500 J </span>
<span>m = 0.4 kg</span>
<span>c = 4180 J/Kg </span>°c
<span>We can take t1 to be 0</span>°c
t2 - 0 = 500 / ( 0.4 * 4180 )
t2 - 0 = 0.30°c
1.0m/s2 because net force and acceleration have a proprtional relationship
The equations of motion can be used to obtain the velocity as 44.7 m/s.
<h3>How are the equations of motion used?</h3>
The equations of motion are used to solve questions that bother on kinematics. In this case, we are dealing with motion under gravity. In order to find the final velocity, we have to use the equation;
v^2 = u^2 + 2gh
- v = final velocity
- u = initial velocity
- g = acceleration due to gravity
- h = height
Since he dropped from a height, u = 0 m/s
v^2 = 0^2 + 2 (10) (100)
v^2 = 2000
v = √2000
v = 44.7 m/s
