Let's work through Newton Laws — Complete Guide with Examples together. Physics problems become simple when you break them into clear, logical steps. Here's exactly how to approach this one.

Quick Answer

See the step-by-step solution above for the complete answer.

Step-by-Step Solution

Step 1: Newton's First Law is about inertia

Step 2: Objects resist changes in their state of motion

Step 3: Example: A ball on a table stays still until pushed

Step 4: F = ma, so a = F/m

Step 5: a = 10/2 = 5 m/s²

Step 6: Newton's First Law is about inertia

Step 7: Objects resist changes in their state of motion

Step 8: Example: A ball on a table stays still until pushed

Step 9: F = ma, so a = F/m

Step 10: a = 20/4 = 5 m/s²

Step 11: Newton's Third Law: every action has an equal and opposite reaction

Step 12: You push wall with 50 N → wall pushes you with 50 N

Step 13: Newton's First Law is about inertia

Step 14: Objects resist changes in their state of motion

Step 15: Example: A ball on a table stays still until pushed

Step 16: F = ma, so a = F/m

Step 17: a = 50/10 = 5 m/s²

Step 18: Newton's Third Law: every action has an equal and opposite reaction

Step 19: You push wall with 50 N → wall pushes you with 50 N

Step 20: Newton's First Law is about inertia

Step 21: Objects resist changes in their state of motion

Step 22: Example: A ball on a table stays still until pushed

Step 23: F = ma, so a = F/m

Step 24: a = 80/6 = 13.333333333333334 m/s²

Step 25: Newton's Third Law: every action has an equal and opposite reaction

Step 26: You push wall with 50 N → wall pushes you with 50 N

Step 39: Newton's First Law is about inertia

Step 40: Objects resist changes in their state of motion

Step 41: Example: A ball on a table stays still until pushed

Step 42: F = ma, so a = F/m

Step 43: a = 70/4 = 17.5 m/s²

Step 44: Newton's Third Law: every action has an equal and opposite reaction

Step 45: You push wall with 50 N → wall pushes you with 50 N

Step 46: Newton's First Law is about inertia

Step 47: Objects resist changes in their state of motion

Step 48: Example: A ball on a table stays still until pushed

Step 49: F = ma, so a = F/m

Step 50: a = 100/10 = 10 m/s²
