Gravity Work & Power of a Lawn Mower & Motion of a Cart

AI Thread Summary
The discussion focuses on solving physics problems related to work, power, and motion. For the first problem, the work done by gravity is calculated using the formula w = Fd, resulting in 700 Joules. The power of the lawn mower is determined by converting the distance to meters and using the power formula, yielding 176 Watts. The cart's final velocity is found using the equation v = sqrt(2as), resulting in approximately 3.16 m/s. The work done by the cart and its final kinetic energy are also calculated, reinforcing the relationship between force, distance, and energy in motion.

Homework Statement



1a) Find the work done by the force of gravity.
Given- Force = 350 Newtons
distance = 2.00
1b) find the power of a lawn mower the time is 30 min and the force is 88 Newtons and the distance is 1.2 km

2a) a 15 kg cart starts from rest, travels 10 meters with a force of 105 Newtons. what is the final velocity?

2b) What is the carts work while pushing down the aisle
2c) what is the carts final kinetic energy?

Homework Equations

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
