Vehicle Braking Distance Calculation: Physics Example
Question: A driver applies brakes on seeing a traffic signal 400 m ahead. At the time of applying the brakes the vehicle was moving with a speed of 15 ms-1 and retarding with 0.3 ms-2 .What is the distance of the vehicle after one minute from the traffic signal? Solution- Braking distance Time taken for…

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…
