1. The problem statement, all variables and given/known data An automobile of mass 1000 kg is traveling 10 m/s. What force is necessary to accelerate it to 50 m/s in 8 sec? 2. Relevant equations Used Sigma(F) = (m)(a) Sigma F = force m = mass a = acceleration 3. The attempt at a solution F = ma Sigma F = (1000)(50-10) And that number is way too high. I don't really know how to approach this problem or even what I should use. Please help. Thank You.
