To find Work Use the Work = Pressure * delta Volume Be sure everything is in SI units 1atm=1.013*10^5 1cm^3=1*10^-5m^3 I have no idea how to find the change in internal energy though sorry

physics
You can use the equation (d=Vit + 1/2 a t^2) So for the first one it would be: d= (0)(1) + 1/2 (1.5) (1^2) And the answer would be .75m Each time just plug in the time to 't' and keep all the other information the same.

Physics
A 15 kg model airplane flies horizontally at point A that is 20 m about point B. It has a speed of 19.993 m/s at point A. It then flies horizontally at point B. If the loss of potential energy is reflected as an increase in kinetic energy, what is the speed of the model airpla...

Physics
In an electronics factory, small cabinets slide down a 30 degree incline a distance of 16 m along the incline to the next assembly stage. The cabinets have a mass of 10 kg each. Calculate the speed each cabinet would acquire if the incline were frictionless. What kinetic energ...

Physics
A 1.5 N force acts on a .20 kg cart so as to accelerate it along a frictionless track. If it is accelerated from rest, how fast is it going after .3m? The answer given is 2.12 m/s but I am not sure how to get to that.

Physics
A .5 kg block is sliding along a tabletop with an initial velocity of .20 m/s. It slides to rest in a distance of .7m. Find the frictional force regarding it motion. The answer given is .0143 N but I do not understand how to get that.
