8.) If the car would be of more weight that means it will have more momentum. So, it will be very hard to stop it in case of any mishap. It will also poise a threat to the safety of the audience. Moreover, more weight means more amount of wood needed, whiich means felling of more trees. So, weight limit is put on.
9.) The x-component of the tension in the string will be equal to the centrifugal force. And the y-component of the tension in the string will be equal to m*g. Solving these equations, g can be calculated.

8) I was a scout when I was a young boy. Each year the scouts would participate in the pine wood derby (look up pine wood derby if don't know what that is). In the pine would derby you build a toy car out of a block of pine wood. Each scout then races their 4 car in a competition, by letting their car go down a ramp. The rules of the pine wood derby dictate that a car can...
please explain the answer 10) A small mass m moves along a hoop of radius R without friction. Attached to the mass is a spring with spring constant k. The other end of the spring is attached to the bottom of the hoop. The equilibrium length of the spring is 0 and the force from the spring on the bead is kr. The mass is placed at the bottom of the hoop and given an initial speed to the right...

i have some physics questions. hopefully you can answer these all please. A block with mass m = 2.0-kg attached to the end of a spring undergoes simple harmonic motion on a horizontal frictionless surface. The oscillation period is T = 5.5-s and the oscillation amplitude is A = 13.8-cm. When the spring is unstretched the block sits at a distance L = 2.2-m from a wall. Suppose we snap the spring at the very moment the block passes through...

ECE Review Worksheet 1 AP Physics Mr. Marrash 1. A space traveler weighs 980 N on Earth. What will the traveler weight on another planet whose radius is 3 times that of the Earth and whose mass is also 9 times that of the Earth. Do not use any numerical values of the universal gravitational constant G, the mass of Earth, or the radius of Earth to get your answer. 2. Two skaters, a man and a woman, are standing...
