X Incorrect The 60-lb boy has taken a running jump from the upper surface and lands on his 12-lb skateboard with a velocity of 14 ft/sec in the plane of the figure as shown. If his impact with the skateboard has a time duration of 0.05 sec, determine the final speed valong the horizontal surface and the total normal force Nexerted by the surface on the skateboard wheels during the impact. 24 14 ft/sec Answers: V= 12.78 ft/sec N= 254 Ib
