#### Answer the following questions and **show** your work! 1. In this **momentum** worksheet students ... โ 5. The two photogates will record the position of carts **as a function of time**. if youโre more dedicated ... (p. According to the second law, the **momentum** of each **changes** at a rate equal to **the force acting** on it. This packet comes with 12. 12. **The graph** **above** **shows** **the force** **on an object** of mass M **as a function** **of time**. the total **change** in the **momentum** ofthe **object** is (A) 40 kg m/s (B) 20 kg m/s (C) O kg m/s (D) -20 kg 'n/s (E) indeterminable unless the mass M of the **object** is known Top Vie w For the **time** interval O to 4 s, 13.. Question:** Force F O Time 0** The graph above shows the force acting on an object as a function of time. The change in momentum of the object from time 0 totis (A) 2F (B) Ft (C) Ft (D) Ft (E) Zero This problem has been solved!.

**object**can also be found by considering the

**force**

**acting**

**on**it. If a

**force**, #F#, acts on an

**object**for

**a**

**time**, #\Delta t#, the change in the

**objects**momentum is #\Delta p= F*\Delta t#. Remember to use the right sign when substituting #F#. For example, a

**force**to the left could be negative.

**The**
