with the horizontal) under the following road conditions. You may assume that the weight of the car is evenly distributed on all four tires and that the coefficient of static friction is involved—that is, the tires are not allowed to slip during the acceleration. Use a coordinate system in which down the slope is positive acceleration. 1.Calculate the maximum acceleration for the car on dry concrete, in meters per square second. 4 significant figures. 2.Calculate the maximum acceleration on wet concrete, in meters per square second. 4 significant figures. 3. Calculate the maximum acceleration for the car on ice, in meters per square second, assuming that μs = 0.100, the same as for shoes on ice. 4 significant figures.
I am working on my homework and keep getting question 1 incorrect. Through a video I followed steps multiple times and keep getting -8.05. I am unsure what I am doing incorrectly.
Consider a car heading down a 9.5° slope (one that makes an angle of 9.5° with the horizontal) under the following road conditions. You may assume that the weight of the car is evenly distributed on all four tires and that the coefficient of static friction is involved—that is, the tires are not allowed to slip during the acceleration. Use a coordinate system in which down the slope is positive acceleration.
