Question

A particle is ejected with an initial velocity of 3m/s, starts moving along a path such that its velocity various quadratically government by F1(t) =-t×t+3t+a for the first 1 hour. after 1 hour its velocity varies linearly,governed by f2(t)=ut+b.here ,a , u , and b are constants. with refrence to this scennario perform the following

Answer 1

$txt + 3t + a$

Answer 2

when the particle can be ejected as a velocity of 3m/s  and it can be moving  along with apathy as given as the equation of quadratical government  by f1(t)  =t x t+3t+a for 1 hour  so after the one hour it can be changed as f2(ut+b. )Here a, b, and u are constants.

According to the equation the answer can be txt+3t+a.
