A0.358 kg particle slides around a horizontal track. the track has a smooth, vertical outer wall forming a circle with a radius of 1.66 m. the particle is given an initial speed of 8.19 m/s. after one revolution, its speed has dropped to 6.29 m/s because of friction with the rough floor of the track. calculate the energy loss due to friction in one revolution.

The energy loss due to friction in one revolution is 4.92 J.

Explanation:

Given that,

Mass of particle = 0.358 kg

Radius = 1.66 m

Initial speed =8.19 m/s

Final speed = 6.29 m/s

We need to calculate the kinetic energy

Using formula of kinetic energy

Put the value into the formula

Hence, The energy loss due to friction in one revolution is 4.92 J.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

i think the answer is a, hope this : )
