find the change n momentum of a 1120-kg car that increases its speed / what minimum force is need to do this?

To find the change in momentum of a car, we need to know the initial and final velocities of the car. However, since you haven't provided that information, we'll assume that the car increases its speed from an initial velocity, v1, to a final velocity, v2.

The formula to calculate the change in momentum is:

Δp = m * (v2 - v1)

where Δp is the change in momentum, m is the mass of the car, and v2 and v1 are the final and initial velocities, respectively. In this case, the mass of the car is given as 1120 kg.

Next, let's calculate the minimum force needed to achieve this change in momentum. According to Newton's second law of motion, the force (F) required to change the momentum of an object is given by:

F = Δp / Δt

where Δt is the time interval during which the change in momentum occurs.

Since we don't have the time information, we can't calculate the exact minimum force required. However, we can determine the minimum force needed assuming that the time interval (Δt) is very small, implying that the acceleration required is very high.

To find the minimum force, substitute the change in momentum (Δp) from the first equation into the second equation:

F = (m * (v2 - v1)) / Δt

Again, without the value of Δt, we can't calculate the exact minimum force required.

In summary, to find the change in momentum of the car, we need the initial and final velocities. To determine the minimum force required, we need the time interval (Δt) or additional information to calculate it.
