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
Answer:
Explanation:
As we know that backpack is kicked on the rough floor with speed "v"
So here as per force equation in vertical direction we know that
so normal force on the block is given as
now the magnitude of kinetic friction on the block is given as
now when bag is sliding on the floor then net deceleration of the block due to friction is given as
now we know that bag hits the opposite wall at L distance away in time t
so we have
