height grou ion along the total path). mechanical energy at point A

sum of the other two forces. The force the worker applies is constant over the distance and is equal to the value F. 4) A cart of mass m1 reaches the bottom of a ramp with an angle 0, going a speed v, and is pulled to the top of a ramp on the cart along the ramp by X Joules (Hint: This means you can write an equation relating the applied force to the at neight n with an applied force that exceeds the work done bv the force of friction plus the work done by gravity e m the space below the necessary diagrams to approach all parts of this problem (there should be two). b) Find an equation for the speed of the cart at the top of the ramp.

A 3.2-kg bucket of water is lifted vertically 2 m How much work against gravity is done?  Use g = 9.8 m/s2 Calculate to one decimal

Write on paper pls A work of 12 J is needed to stretch a certain spring by 30 cm a) What is the force constant of the spring? b) How much work must be done to stretch the spring 4.00 cm? c) When released from rest from 4.00 cm position what would be the speed at the unstretched position?

A medieval baker is disgusted by a rat infestation. In desperation (and apparently having a modestunderstanding of mechanics), he throws a rat in the air straight up at 25.0 m/s. Use energy conservation todetermine the maximum height of the rat

A HUNTER EXERTS AN AVERAGE FORCE OF 100N IN PULLING BACK THE STRIING OF HIS BOW THROUGH A DISTANCE OF 0.50M. WHEN THE ARROW OF MASS 0.20KG IS RELEASED, IT FLIES VERTICALLY UPWARDS CALCULATE THE POTENTIAL ENERGY IN THE BOW JUST BEFORE THE ARROW IS RELEASEDCALCULATE THE MAXIMUM HEIGHT REACHED BY THE ARROW

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A child and sled with a combined mass of 49.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 4.00 m/s at the bottom, what is the height of the hill? m
