1. ### If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward?

...the values given to get the ideal speed Vi: = sqrt (90 * 9.8 * tan(15)) = 15.m/s = (15. / 1000) / (1 / 3600) = 54km/hr For part (b), we need to factor in the frictional force Ff as ...

2. ### I need a scientific term for wind.?

In aerodynamics it is simply called air flow, and it's characterized by its velocity. No special scientific term. Term "wind" is more related to meteorology and weather.

4. ### How much time is needed for a car to accelerate...?

a = (v2 - v1) / t t = (v2 - v1) / a v2 = 21.9m/s v1 = 8.7m/s a = 3m/s2 so t = (21.9 - 8.7) / 3 t = 4.4s Hope this helps.
