Kara Less was applying her makeup when she drove into Kroger's busy parking lot last Friday morning. Unaware that Lisa Ford was stopped in her lane 30 feet ahead, Kara rear-ended Lisa's rented Taurus. Kara's 1300-kg car was moving at 11 m/s and stopped in 0.14 seconds. What was the momentum of Kara's car before the collision?
The momentum of an object can be calculated using the formula:
momentum = mass * velocity
In this case, the mass of Kara's car is given as 1300 kg, and the velocity is given as 11 m/s. Therefore, the momentum of Kara's car before the collision can be calculated as:
momentum = 1300 kg * 11 m/s = 14,300 kg·m/s
So, the momentum of Kara's car before the collision was 14,300 kg·m/s.
