OUTLLLLLAn automobile travelling with an initial velocity of 30m/sec comes to rest after travelling adistance of 90m. Assuming the retardation to be uniform find its value. What time does it taketo cover the distance? (Ans: 6 sec)uloint of Am/sec How high will it rise?

Answer» <p>v*v - u*u = 2asv=otherefore you will get a = 5m/s*suse - before 'a'use s = ut + 1/2at*tyou will get two values for t and take positive value</p> <p>yeue8g in 3rd thresh Irish shut in b wvg bbdjdbsk</p> <p>u=30m/ss=90mv=0then using third eq. of motion 0 - 900=2a×40- 900/80 = a- 90/8=anow , a=( v -u)/t- 90/8 = (0 - 30)/t t =( -30 ×8)/-90t = -240/- 90</p>
