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…

Ratio of Time Taken to Drop Bodies from Different Heights
Question: Two bodies of different masses m1 and m2 are dropped from two different heights a and b.What is the ratio of time taken by the two bodies to drop through these distances. Solution: Ratio of time taken The two objects are striking the ground with velocities v1 and v2 respectively. $${v_1=\sqrt{2gh_1}}$$ $${v_2=\sqrt{2gh_2}}$$ Time taken…

Inclined Plane: Resolving Weight Forces
Question: A mass of 2 Kg lies on an inclined plane as shown below.Resolve its weight along and perpendicular to the plane. (take g=10 ms-2 ) Solution: Inclined plane shopify.pxf.io/1r4onx Resolving the weight into two components The component which is along the plane is $${mg\sin\theta}$$ $${20 \sin\ 30^\circ}$$ $${20 (\frac{1}{2})}$$ $${=10 \ N}$$ The component…
