The sum of final and initial velocity is 17. Acceleration is 10m/s^2 and displacement is .85 m. Find initial and final velocity.
From my observation, i think time is also neede to answer this qn...By the way, is this an mcq?Given,v+u=17 -----(1)(v-u)/t=10ms-2v-u=10ms-2 * t seconds = 10t m/s ----- (2) Solve 1 and 2v=(17+10t)/2Substitute in (1)(17+10t)/2 +u = 1717+10t+2u= 3410t + 2u=17u = (17- 10t)/2 Substitue in (1) v+17+10t =17v+10t=0v= -10tthis is why i said if t was there, answer would be accurate and if anyone knows it more perfect, pls write that too
we know that v+u=17;u=17-vusing 3 eq of motionv^2-u^2=2asby putting value of v in this equation we get vtherefore, v=9and u=8; thnx if it is right tell me
