Assume g= 10 m/sec2 60*x1 + 35*x2 = 1.3*10=13 on observation we get x1= 0.1 m x2= 0.2 m so tan(angle)= .1/.8= .125 angle= 7.125 degree

A car reaches a speed of 40m/s from rest in a time of 8 seconds. After teh 8 seconds, the car travels at a constant velocity fro 200meters when it runs out of gas. The car slowly comes to rest 30 seconds after running out of gas. Calculate acceleration for the first 8 seconds

**math**

we have problem it'sa regular quadilateral example given by u is not correct

**physics**

300 cos 35.2 - Fk = ma fk = 300 cos 35.2 - ma Fn = mg + 400 sintheta = 300 + 400 sin 35.2 Fk = Fn*uk uk = 0.57 300 cos 35.2 - ma = 0.57 [ 300 + 400sin 35.2] -ma = (0.57)[300+400sin35.2]- [300 cos 35.2] a = all that crap on the right side/ (300N/0.9) a = 0.8 m/s2 Sx = VoT+ 1/2 ...
