low temp is low ke, momentum eyc ... molecules hit walls withless speed ....low pressure
<span>The formula to get the Kinetic Energy is KE=1/2mv^2 where m=mass in kilogram and v=velocity of the object. From you given, we substitute it to the variables. This is the solution:
KE=1/2mv^2
KE=1/2(55kg)(9.0m/s)^2
KE=1/2(4455)
KE=2227.5J
or it can be written in scientific notation as 2.2275x10^3J or closest to your choices is 2.2x10^3J.</span>
In this situation we need to use an kinematics equation. Usually I get questions about what is final velocity not speed.
KINEMATIC EQUATION:
Final velocity= initial velocity + acceleration×time
Substitute factors
Final velocity= 30 + 2(4)
Multiply
Final velocity= 30 + 8
Now add
Final velocity (or final speed)= 38 m/s
Now you want to find how long did it travel, we have to use another kinematics equation
KINEMATIC EQUATION:
Distance= initial velocity×time + (1/2)×acceleration× time squared
Substitute
distance= 30(4) + (1/2)(30)(4^2)
Multiply
distance= 120 + (15)(16)
distance= 120 + 240
distance= 360 m
