Tower Height Calculation: Stone Thrown Upward Speed Formula
Question: A stone is thrown upwards with a speed v from the top of a tower.It reaches the ground with a speed 3v.What is the height of the tower? Solution: Thrown up – Sign convention Tower height calculation: Applying third equation of motion $${v^2=u^2+2as}$$ Here initial velocity u=+v Final velocity v= -3v Acceleration due to…

Vertical Ball Motion: Distance and Displacement in 3 Seconds
Question: A ball is thrown vertically upward with a velocity of 20 ms-1.Find Solution: Thrown up- Sign convention https://shopify.pxf.io/c/4884043/1295413/13624 (a) Distance travelled by the ball in first three seconds When a ball is thrown vertically upward, the velocity at its highest point is zero (v=0) Here initial velocity of the ball (u) =20 ms-1 Hence…

Average Speed Calculation: 3/4th and 1/4th Distance
Question: A particle covers 3/4 th of total distance with speed v1 and next 1/4 th with speed v2. Find the average speed of the particle. Solution: $$Average \ speed = \frac{Total \ distance}{Total \ time \ taken}$$ Total distance is $${\frac{3}{4}(d)+\frac {1}{4}(d) =d}$$ Let the speed be v1 for the 3/4 th distance and…
