2. How long does it take for a 50.0 kg rider on a 10.0 kg bike to accelerate from rest to 4.0 m/s [E] if the unbalanced force acting on the bike and rider is 48 N [E]? (ANS: 5.0 s) 3. What change in velocity would be produced by an unbalanced force of 2.0 x 104 N [forward] acting for 6.0 s on a 2.0 x 103 kg dragster?(ANS: 6.0x10 m/s [ND)
