A 2000-kg car is moving at a speed of 10
m/s when it accidentally crashes into a
construction cone parked in the middle of the
road. The 2.5-kg barrel acquires a forward
velocity of 25 m/s. How fast is the car moving
after the collision

The velocity of the car after the collision with a construction cone

is 9.97 m/s.

Velocity of the car after the collision

The velocity of the car after the collision is determined from principle of conservation of linear momentum;

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

2000(10) + 2.5(0) = 2000(v₁) + 2.5(25)

20,000 = 2000v₁ + 62.5

2000v₁ = 19,937.5

v₁ = 9.97 m/s

Thus, the velocity of the car after the collision with a construction cone

is 9.97 m/s.
