calculate-the-maximum-acceleration-of-a-car-that-is-heading-down-140-slope-one-that-makes-an-angle-of-1400-with-the-horizontal-under-the-following-road-conditions-you-may-assume-that-the-wei-82316

Calculate the maximum acceleration of a car that is heading down a 14.0° slope (one that makes an angle of 14.0° 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 deceleration. (Define the positive direction to be down the slope.) Part 1 Calculate the maximum acceleration of the car on dry concrete, with a coefficient of static friction of 0.980. Part 2 Calculate the maximum acceleration of the car on wet concrete, with a coefficient of static friction of 0.690. Part 3 Calculate the maximum acceleration of the car on ice, with a coefficient of static friction of 0.210.

consider-a-1300-kg-car-presenting-front-end-area-260-mathrmm2-and-having-drag-coefficient-0340-it-ca

Consider a 1300 -kg car presenting front-end area $2.60 \mathrm{m}^{2}$ and having drag coefficient $0.340 .$ It can achieve instantaneous acceleration $3.00 \mathrm{m} / \mathrm{s}^{2}$ when its speed is $10.0 \mathrm{m} / \mathrm{s}$ Ignore any force of rolling resistance. Assume that the only horizontal forces on the car are static friction forward exerted by the road on the drive wheels and resistance exerted by the surrounding air, with density $1.20 \mathrm{kg} / \mathrm{m}^{3}$. (a) Find the friction force exerted by the road. (b) Suppose the car body could be redesigned to have a drag coefficient of $0.200 .$ If nothing else changes, what will be the car's acceleration? (c) Assume that the force exerted by the road remains constant. Then what maximum speed could the car attain with $D=0.340 ?(\mathrm{d}) \mathrm{With} D=0.200 ?$

00:01 So let's call the car having a massive m.
00:04 That doesn't really matter for now, but we're just going to say.
00:09 And we're given an angle of 14 degrees.
00:13 So we draw a free body diagram.
00:21 Here's a horizontal.
00:23 Here's 14 degrees...
