Answer:
the average kinetic energy of water particles - C.
Answer:
8.2 m/s²
Explanation:
m = mass of the block
μ = Coefficient of kinetic friction = 0.17
= Normal force on the block by the ramp
= kinetic frictional force
Force equation perpendicular to ramp surface is given as
Kinetic frictional force is given as
Force equation parallel to ramp surface is given as
m/s²
Answer:
16.45 m/s
Explanation:
Let y be the vertical distance and x be the horizontal distance
We are given that
The altitude of hang glider increasing at the rate=
The shadow of the glider moves along the ground at speed=
We have to find the magnitude of glider's velocity.
We know that
Magnitude of velocity=
Substitute the values
Hence, the magnitude of glider's velocity=16.45 m/s
