A car that's initially traveling at 10 m//s accelerates uniformly for 4 seconds at a rate of 2 m//s^(2) in a straight line. How far does the car travel during this time ? |

Answer» Solution :We're GIVEN `v_(0), t, and a`, and we're asked for s. So v is MISSING it isn't given and it isn't asked for , so we use Big Five #2. `DELTA s= v_(0) Delta t+(1)/(2)at^(2)=(10 m//s)(4 s)+(1)/(2)(2m //s^(2))(4 s)^(2)=56 m` |
