Problem 45E

A 1125-kg car and a 2250-kg pickup truck approach a curve on a highway that has a radius of 225 m. (a) At what angle should the highway engineer bank this curve so that vehicles traveling at 65.0 mi/h can safely round it regardless of the condition of their tires? Should the heavy truck go slower than the lighter car? (b) As the car and truck round the curve at 65.0 mi/h, find the normal force on each one due to the highway surface.

Step-by-Step Solution:
Step 1 of 3

Hypothesis testing Null hypothesis  use “=” signs  Assume null hypothesis is true until you find evidence to reject  Status quo, no change  Mean of normal distribution P value  Equivalent to probability, small evidence against the null  If p value is low the null shall go, which mean if the p value is lower than the null you have enough evidence to reject it. Alternative hypothesis  Tells us what probability we are calculating under the curve  Uses signs =  Experimental hypothesis Level of significance  A p value that is used to determine if we will accept or reject the null hypothesis.  If you reject null hypothesis then you are saying that the alternative hypothesis is true. Practical Significance: deciding if the result is actually important
