A car starts motion from rest at uniform acceleration of 2m/sec 2 for 3 seconds, and then it maintains a constant speed for 2 seconds.Then the breaks are used to decelerate the car uniformly to rest
HOW DISPLACEMENT,ACCELERATION ACTS IN REAL LIFE PLZ GIVE SOME EXAMPLE. (The question was posted by Chandrima ) Answer: As you know, the displacement is the shortest distance between two points ; the initial point and the final point. The displacement is independent of the path followed by the object and this itself is the beauty [...]
A spy report about a suspended car reads as follows.”the car moved 2.00 km towards east,made a perpendicular left turn, ran for 500 m, made a perpendicular left turn, ran for 4.00 km and stopped”. Find the displacement of the car. Answer: 2061.5 m https://www.facebook.com/groups/askphysics/ Incoming search terms:spy vectorvectorvector addition problemvectors in physics csun [...]
Is the equation for displacement in the n th second dimensionally correct?
S = u + a (n- 1/2)
See the explanation given by Vimal Raj
If we notice the derivation of this formula
“A body covers a distance of 20 m in 7th s and 24 m in the 9th s. How much shall it cover in 15s ?” - Raghav posted this question. Answer: From the eqn for displacement in the nth second, For the displacement in the 7th sec, we get, …………………….. (1) For the displacement in [...]
