Acceleration =the change in velocity per unit time.... 1. A net force of 10n is applied to a 5 kg mass. By how much does the body accelerate? Given: F = 10n; M = 5kg Required: A Solution F= ma A= f/m = 10 N/ 5kg = 10 k - m/s 2 / 5 k =2 m/s 2 (Divide the 10 to 5 and the answer is 2 m/s 2) 2. What jet force is needed to accelerate a 10- kg object by 3 m/s 2? Given: m= 10kg ; a= 3m/s Required= F Solution: F = ma = (10kg) (30 m/s2) = 30 kg - m/s2 =30 N :)
