Answer:
The transnational kinetic energy of the yo-yo is 0.083 J.
Explanation:
Given that,
Force=0.24 N
Distance in up= 0.17 m
Distance in down = 0.26 m
Mass of yo-yo = 0.057 kg
Initial speed = 2.4 m/s
Suppose we find the increase in the transnational kinetic energy of the yo-yo
The transnational kinetic energy is equal to the change in potential energy.
We need to calculate the transnational kinetic energy of the yo-yo
Using conservation of energy
Where, F = force
h = height
m = mass of yo-yo
Put the value into the formula
Hence, The transnational kinetic energy of the yo-yo is 0.083 J.
Answer:
17.5 m/s²
1.90476 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Force
Initial acceleration of the rocket is 17.5 m/s²
Time taken by the rocket to reach 120 km/h is 1.90476 seconds
Change in the velocity of a rocket is given by the Tsiolkovsky rocket equation
where,
= Initial mass of rocket with fuel
= Final mass of rocket without fuel
= Exhaust gas velocity
Hence, the change in velocity increases as the mass decreases which changes the acceleration

Heya!!!
Answer to your question:
C.
Energy transferred to a machine equals energy transferred from it.
Law of conservation of energy states that total energy of an isolated system remains constant
Energy can neither be created nor be destroyed. Machine follows the same rule.
Hope it helps ^_^
