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
The answer is either harmonic motion or simple harmonic motion.
Answer:
1.78 x 10² kg
Explanation:
KE = ½mv²
m = 2KE/v² = 2(2e4)/(54/3.6)² = 177.777...
