A 1600 kg sedan goes through a wide intersection traveling from north to south when it is hit by a 2000 kg SUV traveling from ea
st to west. The two cars become enmeshed due to the impact and slide as one thereafter. On-the-scene measurements show that the coefficient of kinetic friction between the tires of these cars and the pavement is 0.75, and the cars slide to a halt at a point 5.42 m west and 6.37 m south of the impact point.How fast was sedan traveling just before the collision? How fast was SUV traveling just before the collision?

Explanation:
From the exercise we got the ball's equation of position:
a) To find the average velocity at the given time we need to use the following formula:
Being said that, we need to find the ball's position at t=2, t=2.5, t=2.1, t=2.01, t=2.001
