Question

I do not know how to find the work in 3(c) since I don't know the force. Help please.

K: 500 N/m
Ax= 3meters
MK = 0.3
Ax 10 metてry
Imeters
50°

3)
The 15 kg object starts at rest. The
spring
is compressed 3 meters. Calculate the speed
os the object at point "a", where all of the
springs potential energy
the 7s Kg objects Kinetic eneryy.
has been converted to
Calculate the speed of the object after it
has slid down a ramp (no Sriction) 1 meters.
Calculate how much negative work the grass
does on the s Kg object, What is the speed of
the object after the grass?
Have the 15 kg object do one more task! It
can go up a hill, down a
hill, hit a
spring
(if so, calculate how Jar the spring compresses until
the object stops),
or across some grass. Use two
decimal places, so
that
your
task is unique !
