Answer:
d = 0.391 m
Explanation:
given,
mass of sled = 18 kg
inclined at an angle of = 28°
kinetic friction between the sled and inclined = 0.25
using energy equation
d = 0.391 m
hence, the distance traveled by the sled is equal to 0.391 m
Matter is radioactive and decays over time
Henri Becquerel discovered that <span>uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.

Those forces are exactly equal.
Gravity always works as a pair of <em>EQUAL</em> forces ... one in each direction
between two masses. Your weight on the Earth is exactly the same as
the Earth's weight on you.
114 kmh is the average speed.
= 1425/12.5
