1. The problem statement, all variables and given/known data 1. A 340 kg rocket sled can be accelerated at a constant rate from rest to 1900 km/h in 2.6 s. What is the magnitude of the required net force? 2. Relevant equations 3. The attempt at a solution 1. So I tried calculating the acceleration and multiplying it by the mass. For the acceleration I tried dividing 1900km/h by 2.6s and multiplying it by the mass however that did not work.
