**A**

__1,662 kg__car goes from__14 m/s__to__29 m/s__in__19 secs__.**What is the**

__average force__acting upon it? Write your answer to two decimal places.**Attempt:**

**Mass**= m =

__1,662 kg__

**Initial Velocity**= V

_{i}=

__14 m/s__

**Final Velocity**= V

_{f}=

__29 m/s__

**Time**= t =

__19 secs__

**Acceleration**= a = Δvelocity/time = (V

_{f}- V

_{i})/t = 15/19 =

__0.7894736842105263 m/s__

^{2}**Force**= F = m x a = 1,662 x 0.7894736842105263 =

__1312.105263157895 N__

**Answer:**

**Average Force**=

**1312.11 N**

**Is the answer correct?**
