D Question 8 2 pts Suppose two children push horizontally, but in exactly opposite directions, on a third child in a wagon. The first child exerts a force of 67.9 N, the second a force of 94.8 N, friction is 10.8 N. The mass of the third child plus wagon is 24.2 kg. Calculate their acceleration. D Question 9 2 pts A MotoGP motorcycle has an acceleration of 3.41 ms"2 while traveling at a speed of 96.7 km/h. At that speed the forces resisting motion, including friction and air resistance, total 372 N. (Air resistance is analogous to air friction. It always opposes the motion of an object.) What force does the motorcycle exert backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 333 kg? D Question 10 2 pts An Olympic 100m sprinter accelerates for 3.37 s to reach her maximum speed, and then maintains that top speed for the rest of the race. If she takes 10.86 s to reach the finish line, calculate her maximum speed. Please give your answer to 3 significant figures
