Answer:
weight!!!! Free fall is the motion of a body where its weight is the only force acting on an object.
Answer:
The distance travel by block before coming to rest is 0.122 m
Explanation:
Given:
Mass of block kg
Initial speed of block
Final speed of block
Coefficient of kinetic friction
Ramp inclined at angle 28.4°
Using conservation of energy,
Work done by frictional force is equal to change in energy,
Where
m
Therefore, the distance travel by block before coming to rest is 0.122 m
K.E.= 1/2 x MV^2 = 1/2 x 40(kg) x (25x25) =12500J
