A 1500kg car has the same momentum as a 2500kg truck moving at 15 m/s.
How fast is the car moving?
A. 15 m/s
B. 25 m/s
C. 35 m/s
D. 40 m/s
E. 50 m/s
Homework Equations
p = mv
The Attempt at a Solution
Truck = (2500kg)(15m/s) = 37500
Car = v=p/m = 37500/1500kg = 25m/s
This is what I answered but it says it wrong.
Any help would be appreciated.

Momentum (p) is calculated by multiplying an object's mass (m) by its velocity (v). The formula for momentum is p = m x v.
The unit of measurement for momentum is kilogram-meter per second (kg*m/s).
To calculate the speed of the car, we can rearrange the formula for momentum to solve for velocity. The formula for velocity is v = p/m. Therefore, the speed of the 1500kg car is 25 kg*m/s divided by 1500kg, which equals 0.0167 m/s.
Yes, the mass of an object does affect its momentum. The greater the mass, the greater the momentum, assuming the velocity remains constant.
Yes, an object with a lower mass can have the same momentum as an object with a higher mass if the velocity of the lighter object is significantly higher than the velocity of the heavier object.
