Two workers are delivering a load of mass M along an uphill roadwith a
length L and elevation angle q. Worker 1 carries the load whileworker 2
is rolling it in a cart. Find the values of the work W done by eachworker

hi,

i have 5 questions i need the complete solutions with theirfinalresults. is there anyone could help me, i wouldappreciatethat.



1)A worker pushes a sled with a force of 40 N over
a level distance of 6.0 m. If a frictional force of 24 N actsonthe
wheelbarrow in a direction opposite to that of the worker, whatnetwork is
done on the wheelbarrow?



2)
A horizontal force of 200 N is applied to a
55-kg cart across a 10-m level surface. If the cart acceleratesat2.0 m/s2,
then what is the work done by the force of friction as it actstoretard the
motion of the cart?



3)
If both mass and velocity of a ball are tripled,
the kinetic energy is increased by a factor of:

a) 9, b) 12, c) 3, d) 6



4)
A 1 200-kg automobile moving at 25 m/s has the
brakes applied with a deceleration of 8.0 m/s2. How far does thecartravel
before it stops?



5)
Samantha pushes a 50-N crate up a ramp 25.0 m in
length and inclined at 10° with the horizontal. Whatpotentialenergy
change does the crate experience?



thank you in advance

A block of mass 5.0kg is moving down a frictionless inclinethatmakes an angle of 30 degrees with the horizontle . While theblockis moving a distance of 2m, a rope exerts a constat force of15 Nupward along the ramp. throughout the problem useg=10m/s2

a) draw the forces along the block

b) draw a vector to represent the net force on the block. Labelitclearly and determine its magnitude.


c)Is the block speeding up or slowing down explain

d) Find the work done by the net force

diagram below




e) find the work done by each of the individual forces

f) find the total work done by adding up individualcontributionsyou found in part e. is your answer equal to the valueyou found inpart (d)?
