... 5. A 50 kg skater pushed by a friend accelerates 5 m/sec2. How much force did the friend apply? F = ma f= 50 x 5 f= 250 N How fast was she going after 1.2 seconds? 6 m/s 6. A force of 250 N is applied to an object that accelerates at a rate of 5 m/sec2. What is the mass of the object? F = ma 250N=(m ...
