An experimental automobile driven by Wanielle Dalker is traveling at 90 km/h on level ground and then coasts up a hill. (a) Neglecting friction, how high above the level ground will Wanielle and the car go before stopping?
Homework Answers
The vehicle is travelling at a constant speed, this suggests that the acceleration is zero.
When the vehicle will start up the slope, as the friction is negligible, so for the vehicle to continue up the slope
ma = mg
Which will not be possible in the given case due to constant speed. Hence the car will stop immediately.
