a student tests the second law of motion by accelerating a block of ice at a rate of 3.5 m/s squared. if the ice has a mass of 12.5 kg , what force must the student apply to the ice
Newton's second law states that: [tex]F=ma[/tex] i.e.: to accelerate an object with mass m with an acceleration of a, we must apply a force of intensity F. In our problem, the block has a mass of m=12.5 kg, and its acceleration is [tex]a=3.5 m/s^2[/tex], so the force applied is [tex]F=(12.5 kg)(3.5 m/s^2)=43.74 N[/tex]
