Question 568206
First find the acceleration of the car. We have

*[tex \LARGE a = \frac{80 kph - 44kph}{10 s} = 3.6 \frac{kph}{s}] (kilometers per hour, per second). However we want to convert kilometers per hour to meters per second. 1 kph is roughly .2778 m/s, and it turns out that 3.6 kph/s is exactly 1 m/s^2. So a = 1 m/s^2.

We use F = ma to obtain

*[tex \LARGE F = (1500 kg)(1 \frac{m}{s^2}) = 1500 N]
