Question

A cyclist driving at 5m/s picks a velocity of 10m/s over.A distance of 50m/s calculate acceleration and time

Answer 1

Answer:

the acceleration is 10m/s

the time is 5

thank you

Answer 2

Answer:

$INITIAL VELOCITY (u)= 5 m/sFINAL VELOCITY(v) = 10 m/sDISTANCE COVERED(s) = 50 m\\\\\\Using 3^{rd} Formula\\v^{2}  =u^{2} +2as\\10^{2} =5^{2} +2*a*50\\100=25+100a\\75=100a\\a=75/100\\a=0.75  ms^{-2} \\------------------------------\\\\Using  1^{st} Formula\\v=u+at\\10=5+0.75*t\\5=0.75t\\t=5/0.75\\t=6.66666.....s$
