Question

The position of a particle moving on X axis is given by x= At^2 + Bt + C .The numerical value of A B and C are 7 (-2) and 5 respectively and SI units are used. Find
1) the average velocity during the interval t = 0 to t = 5
2) the average acceleration during the interval t = 0 to t = 5

Answer 1

1)find x at t=0 & at t=5 then apply x2-x1/t2-t1 to find av velocity where x2 and x1 are the distances at t=5 and t=0 respectively

2)first find vel. by differentiating x with respect to time
and then in the equation of vel put values t =0&5 and obtain the respective. velocities then apply the formula V2-V1/t2-t1 to get av. acc

if u hav doubt tell me i will provide u the Snap of the solved answer
