Name: Date: Period: Force Calculation Practice A 25 kg biker is riding their bike down the street with a force of 35N. A sudden gust of wind pushes back the biker with 20N. What is the acceleration of the biker? A fish is swimming in an ocean at an acceleration of 5 m/s2. The fish swims against a current of 5N with a force of 23N. Calculate the mass of the fish. An ice skater is ice skating at an acceleration of 12 m/s2 with a force of 30N. What is the skaters mass? A dog is running around chasing his tail using a force of 30N. The dog has a mass of 23 g. What is the dogs’ acceleration? Teacher Page Thank you for downloading my FREE activity! I hope you find this useful in the classroom.
