Uniform Acceleration: Magnitude and Displacement Calculation
Question: A particle starts from the origin with uniform acceleration.Its dislacement after t seconds is given by the relation $${x=2+5t+7t^2}$$ Calculate the magnitude of its Solution: (1) Initial velocity: The displacement of the particle after t seconds is given by the relation $${x=2+5t+7t^2}$$ The velocity of the particle can be found by differentiating the dislacement…

Circular Orbit Speed Calculation for Satellite: 42250 Km Radius in 24 Hours
Question: An artificial satellite is moving in a circular orbit of radius 42250 Km.Calculate its speed if it takes 24 hours to revolve around the earth. Solution: Circular orbit speed calculation: $${Speed =\frac{Distance \ travelled}{Time \ taken}}$$ Speed of the artificial satellite=$${\frac{Distance \ travelled \ by \ the \ satellite}{Time \ taken \ by \…

Gravity Motion Problem: Analyzing Velocity and Distance
A body is thrown up with a velocity 100 ms-1. It travels 5 m in the last second of its journey.If the same body is thrown up with a velocity 200 ms-1, how much distance (in metre) will it travel in the last second? (take g=10 ms-2) Question: Solution: Distance travelled in the last second…

Rocket Vertical Acceleration: Calculating Time to Reach Maximum Point
Question: A rocket is fired vertically up from the ground with a resultant vertical acceleration of 15 ms-2.The fuel is finished in 1 minute and it continues to move up.What is the time taken for the rocket to reach its maximum point? (take g =10 ms-2 ) Solution: Vertical acceleration- calculating time to reach maximum…
