QUESTION 8 A car of mass 1000kg is at the top of a 10 degree hill as shown. What is its gravitational potential energy relative to the bottom of the hill? 10 50 m U - 1000kg X 9.8m/s 2x som X tan(10) - 8.6x104 OU-1000kg x 50m - 5.0 X 105 OU-1000kg x 9.8m/s 2 x 50m X sin(10) - 3.5 x 10 4 OU - 1000k8 X 9.5m/s2 x som X 10 -1,9109 OU-1000kg X 0.8m/s2 x 50m - 4.9 X 105
QUESTION 9 of the car rolls down the hill (with the engine off with negligible friction and air resistance, what will its kinetic energy be when it reaches the bottom of the hill? Note about format if using scientific notation. This system uses E in place of x10 so for example to enter 3x10-24 type 36-24 in the answer box QUESTION 10 Suppose instead that the amo of work done on the car by the frictional and air resistance forces as the car rolls down the hill is 50.000). What then the kinetic energy of the car when it reaches the bottom of the hill? Note about format if using scientific notation. This system uses E in place of x 10 so for example to enter 3x10 -24 type 35-24 in the answer box
