Question

can someone answer C, I feel like im doing it correctly but keep gettting told my answer is wrong. thank you.

Calculate the maximum deceleration (in assume that the weight of the car is evenly )of a car that is heading down a 12.5 slope one that makes an angle of 12.5° with the horontal) under the following road condition. You may tributed on all four tres and that the state coefficient of friction is involved that is, the tires are not allowed to slip during the deceleration (a) on dry concrete A me () on wet concrete 46 W (c) on ice, assuming than 0.100, the same as for shoes on

Answer 1

c)

acceleration along ramp

a = u g cos x - g sin x

a = 9.8* ( 0.1* sin 12.5 - sin 12.5)

a = - 1.164 m/s^2

Note: you can neglect negtive sign in orde rto have magnitude only

Comment before rate in case any doubt, will reply for sure.. goodluck
