A cyclist riding at 15 m/s suddenly applies brakes producing a net force of -600 N. If the mass of the cyclist and bike is 75 kg, calculate the time taken to come to a stop.
💡 Hint: Use the acceleration and initial speed to find the stopping time.
If a 450 kg car is moving with constant velocity and experiences a 900 N force braking it, determine its acceleration. Then, find stopping distance from 30 m/s to 0.
💡 Hint: Solve for acceleration first and then apply kinematics for distance.
