A grocery cart with mass of 16 kg is being pushed at constant speed up a flat 14° ramp by a force Fp which acts at an angle of 17° below the horizontal. Part A Find the work done by each of the forces (mg,FN,FP) on the cart if the ramp is 12 m long.

M PAMP7 ** F20 A student pulls a crate of mass M up the inclined surface the distance d. The surface rises 0 degrees above the horizontal, as shown in the figure How much work does gravity do on the crate? Please use the following values: M = 11.9 kg, 0 = 26.9°, d = 5.88 m, g 9.80 m/s (PAMP716F20) a) 0612 J b) О310J c) O-612 J d) 0 686 J e) O-310 J

part D only needing help with, thanks !

ACTIVITY 4: DECODE THE MESSAGE Directions: Determine the work done by the force on a given system in the following problems. Then, decode the message. I hv a e 4 Displacement (m E You pull your bag with a force of 30 N parallel to the ground classroom 20 m away. How much work will you do on your bag? MA crate is being lifted into a truck. If it is moved with a 2470 N force and 3650 J of work is done, then how far is the crate being lifted? M You must exert a force of 4.5 N on a book to slide it across a table. If you do 2.7 J of work in the process, how far have you moved the book? towards your

A box is pulled 2.0 meters along a rough surface at constant velocity using 100 N force inclined at 30° above the horizontal.  a.If the force applied, Fa is doubled but the frictional force remains the same (this is unlikely to occur in practice since normal force changes), will the net work be the same? b. Is Fa is doubled with the frictional force unchanged how much kinetic energy would the block have after being pulled 2.0 m?

Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.2×106 N, one an angle 16° west of north and the other an angle 16° east of north, as they pull the tanker a distance 0.76 km toward the north. Part A What is the total work they do on the supertanker? Express your answer in joules. VE ΑΣΦ W = ?

On a horizontal surface with µk = 0.70, a 5kg object is dragged with 350N force directed due East. a. Draw all forces, and calculate the work done by each force if the object moves from 3 m to 10 m on the x-axis. Calculate the total work.

The force on a particle is directed along an x axis and given by F = Fo(x/xo - 1) where x is in meters and F is in Newtons. If Fo= 1.5 N and Xo = 5.8 m, find the work done by the force in moving the particle from x = 0 to x = 2x0 m. Number i Units

A 50-N crate initially has kinetic energy 10.0 J at the top of a rough incline of 60 degrees.   A constant horizontal force is applied to the crate as it moves down the incline in dynamic equilibrium.    Is the work from the following forces positive, negative or zero?   Explain your reasoning. Normal, Weight, Applied and Friction Is the net work positive, negative or zero?  Explain your reasoning. How do your answers for (a) and (b) change if the crate is displace up the incline instead?
