Abat strikes a 0.145-kg baseball. just before impact, the ball is traveling horizontally to the right at 55.0m/s , and it leaves the bat traveling to the left at an angle of 40? above horizontal with a speed of 60.0m/s . the ball and bat are in contact for 1.85ms .part afind the horizontal component of the average force on the ball. take the x-direction to be positive to the rightpart bfind the vertical component of the average force on the ball.

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j ?

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
