3. [-/4 Points] MY NOTES DETAILS OSCOLPHYS2016 7.2.P.012. ASK YOUR TEACHER force in (b) = force in (a) PRACTICE ANOTHER (a) Calculate the force (in N) needed to bring a 1000 kg car to rest from a speed of 80.0 km/h in a distance of 120 m (a fairly typical distance for a non-panic stop). N (b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a).
