Answer:
Since the weight of the ant is not given, we cannot determined the work done.
Explanation:
Given parameters:
Distance covered = 150m
Unknown:
Work done by mouse = ?
Solution:
To solve this problem, we need to understand that work done is the force applied to move a body through a certain distance.
In this case, work done;
Work done = force x distance
Work done = Weight x distance
Since the weight of the ant is not given, we cannot determined the work done.
The average salinity of seawater is approximately 3.5%, or 35 per thousand.
To look for the acceleration, it will come from:
vf^2=v0^2+2ad
where:
vf = final velocity = 0
v0 = initial velocity =251 m/s
a = acceleration
d= distance traveled = 0.237 m
0=251^2+2a(0.237 )
a= -251 ^2 / (2*0.237) =-132 913.502 m/s/s
we find the force from:
F = ma = 0.0115kg*(-1.32x10^5m/s/s) = -1518 N
the negative sign shows that the force is in the direction contradictory the
bullet's motion
force of friction on the cart is given as
here we also know the reaction force due to surface
so we can say reaction force is given as
now by force balance we will say
also we know that
now minimum force required to set this into motion
here we know that
So it will require 259 N minimum force to move it
