MY NOTES ASK YOUR TEACHER A particle of mass 2.4 kg moves under the influence of the force F(x) = ( ) N. If its speed at x = 2.1 m is v = 6.8 m/s, what is its speed (in m/s) at x = 7.1 m? m/s 15 DETAILS OSUNIPHYS1 8.3.P.038. MY NOTES ASK YOUR TEACHER A 110 kg man is skiing across level ground at a speed of 8.3 m/s when he comes to the small slope 1.4 m higher than ground level shown in the following figure. 8.0 m- 1.4 m (a) If the skier coasts up the hill, what is his speed (in m/s) when he reaches the top plateau? Assume friction between the snow and skis is negligible. m/s (b) What is his speed (in m/s) when he reaches the upper level if a 60 N frictional force acts on the skis? m/s Submit Assignment Save Assignment Progress
