Challenge Problems
Push your limits with challenges.
Question 1
A 1500 kg car accelerates to a speed of 20 m/s from rest. Calculate the force required if the acceleration is constant over 5 seconds.
💡 Hint: Focus on breaking the problem down into finding acceleration first.
Question 2
In a head-on collision, a 2 kg ball moving at 10 m/s collides with another ball of mass 3 kg at rest. If they stick together, what is their speed after the collision?
💡 Hint: Use conservation principles to analyze pre and post-collision states.
