The change in velocity is 10 m/s in 5 seconds.
sinces a = change in velocity/time
a= 10/5
a=2
Answer:
PEgrav = m *• g • h
Explanation:
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
Hope this helps
Answer:
Kinetic energy is the energy by virtue of object's motion whereas Thermal energy is the internal energy of an object due to the kinetic energy of its atoms. On Increasing temperature, they both increases

Explanation:
Answer:
L = L0 ( 1 - v^2/c^2))1/2 where L0 is the proper length
L = 10 L-y (1 - .9^2)^1/2 = 4.36 L-y length of pole measured by ship
t = 4.36 L-y / .9 c = 4.84 y since the ship travels at .9 c
Work = (force) · (distance)
a). The wind does work on the windmill.
b). The person does work on the box.
c). The metal bar exerts force on the leaning wall,
but nothing moves, so there's no work done.
d). The explosive inflator does work on the airbag, and very soon
after that, the driver and passengers do work on it too.
