Braking causes the vehicle speed to change from 102 km/hr to 27 km/hr over a distance of 70 m. Determine the angle of the hanging graduation tassel during this constant acceleration. Report the angle phi in degrees.The tassel described in P7 has a mass of 48 g. A massless string secures the tassel to the rear view mirror. Determine the tension in the string under the braking conditions described in P7. Report the result in mili-Newtons
