Q) A Body Of Mass 1 Kg And Initial Velocity 10 m/s Is Sliding On A Horizontal Surface. If The Coefficient Of Kinetic Friction Between The Body And The Surface Is 0.5. Then Find The Work Done By Friction When The Body Has Transversed A Distance Of 5m Along The Surface.


Ans) Calculating the Work Done by Friction

Here's how to find the work done by friction when the body transverses 5 meters on the horizontal surface:

1. Calculate the frictional force:

First, find the normal force, which is equal to the body's weight since it's on a horizontal surface:

Normal force (N) = mass (m) * gravity (g) = 1 kg * 9.81 m/s² = 9.81 N



Next, calculate the friction force (F_f) using the kinetic friction coefficient (μ_k):

Friction force (F_f) = μ_k * normal force (N) = 0.5 * 9.81 N = 4.905 N



2. Find the work done by friction:

Work (W) is the force (F) applied along the direction of displacement (d):

Work (W) = friction force (F_f) * distance (d)

Work (W) = 4.905 N * 5 m = 24.525 Joules



Therefore, the work done by friction when the body transverses 5 meters on the surface is 24.525 Joules.

Note:- This work done by friction is negative because it opposes the direction of the body's movement. This energy is dissipated as heat due to friction.

A Bug Crawls Towards The Rim With A Constant Speed Vo Along The Spoke Of A Wheel That Is Rotating With Constant Angular Velocity W About A Vertical Axis. Find All Apparent Forces Acting On The Bug. And How Far The Bug Can Crawl Before It Starts To Slip, Given That Coefficient Of Static Friction Between The Bug And The Spoke Is Us.

Q) A Bug Crawls Towards The Rim With A Constant Speed Vo Along The Spoke Of A Wheel That Is Rotating With Constant Angular Velocity W About A Vertical Axis. Find All Apparent Forces Acting On The Bug. And How Far The Bug Can Crawl Before It Starts To Slip, Given That Coefficient Of Static Friction Between The Bug And The Spoke Is Us. Ans)  Apparent Forces Acting on the Bug: There are three apparent forces acting on the bug: Centrifugal Force (Fc) :   This outward force arises due to the bug's circular motion along the rotating wheel. Magnitude: Fc = mv^2/r, where m is the bug's mass, v is its instantaneous velocity relative to the rim (sum of crawling speed and tangential velocity due to wheel rotation), and r is the distance from the bug to the wheel's axis. Direction: Radially outward, away from the wheel's axis. Normal Force (Fn):   This is the force exerted by the spoke on the bug perpendicular to its motion. Magnitude: Fn = N, where N is the reaction force due to t...

A Damped Harmonic Oscillator Has The Amplitude Of 20cm. It Reduces To 2cm After 100 Oscillations Each Of The Time Period 4.6s. Calculate Its Logarithmic Damping Constant. Compute The Number Of Oscillations In Which The Amplitude Drops By 50%

Q) A Damped Harmonic Oscillator Has The Amplitude Of 20cm. It Reduces To 2cm After 100 Oscillations Each Of The Time Period 4.6s. Calculate Its Logarithmic Damping Constant. Compute The Number Of Oscillations In Which The Amplitude Drops By 50%. Damped Harmonic Oscillator Calculations Here's how we can calculate the logarithmic damping constant and the number of oscillations for a 50% drop in amplitude for the given damped harmonic oscillator: 1. Logarithmic Damping Constant: The logarithmic damping constant (δ) represents the rate of decay of the amplitude per oscillation. We can calculate it using the formula: δ = (1 / N) * ln(A₀ / A_f) where: N is the number of oscillations (100 in this case) A₀ is the initial amplitude (20 cm) A_f is the final amplitude after N oscillations (2 cm) Plugging in the values, we get: δ = (1 / 100) * ln(20 / 2) ≈ 0.02303 Therefore, the logarithmic damping constant is approximately 0.02303. 2. Number of Oscillations for 50% Drop: We want to find the n...
