I’m working on a physics test / quiz prep and need support to help me understand better.ques1: An 18.0 kg cart is pushed along a horizontal surface at 3.50 m/s. When you stop pushing the cart, it comes to a stop after 1.55 m. Calculate m , the coefficient of friction.ques2:
There are a number of communities and monasteries that live in buildings on top of cliffs. These places get there food and supplies by hauling it up from below.In this scenario, 3 loads are being hauled up at the same time. On top is a load of food (64.0 kg), which is tied by a rope to some firewood (49.0 kg) which is tied by more rope to some bricks (135 kg) on the bottom.
a) What force is needed to accelerate the supplies by 0.390 m/s^2?
b) What is the tension on the rope between the food and the firewood?
