WebCorrect option is C) When the horse pulls the wagon, it pushes the ground in the backward direction. Due to the third law of motion, the ground exerts a forward force which has the same magnitude. As the backward force applied by the wagon is weaker than the force applied by the horse, the wagon moves in the forward direction. Web`=>F= 8000\ kg xx 1.944ms^(-2)` `=>F=1552 N` Thus, (a) The net accelerating force = 35000N (b) The acceleration of train = 1.944 ms –2 (c) The force of wagon 1 on 2 = …

(b) The acceleration of the train - Vedantu
WebOct 25, 2024 · Answer: Explanation: Let say the empty wagon has mass "M" now by newton's II Law we will have now it is given that empty wagon is pulled with acceleration 1.4 m/s/s now we will have now a child of mass three times the mass of wagon is sitting on the empty wagon so here we have so we have Advertisement Advertisement WebBill's wagon weighs 10 pounds, and Tom's wagon weighs 20 pounds. Bill is pulling his wagon with twice the force that Tom is. How do the wagon speeds compare? answer choices Both wagons will be moving at the same speed. Bill's wagon is moving 4 times faster than Tom's. Tom's wagon is moving 4 times faster than Bill's. WebOct 30, 2024 · - Backward: the force of friction, which is. So, the equation of motion is. where. m = 20 kg is the mass of the wagon. a is the acceleration. In this part, the wagon is moving at constant speed, so a =0 and the equation becomes. Therefore, we can find the pulling force: (b) 43.9 N. In this case, the acceleration is. So, the equation of motion ... how to save the planet essay
