    Calculators Troubleshooting My Unresponsive TI-89

    Sorry for the late reply. I got my calculator out of the car after a couple days and it worked perfectly again. The car acted as a makeshift reflow oven and took care of the bad connections that were causing the freezing to happen. So if anyone wants to try this, take the batteries out of the...

    Radiation Problem: Solving Homework to Maintain 47°C for Bees

    Homework Statement The giant hornet Vespa mandarinia japonica preys on Japanese bees. However, if one of the hornets attempts to invade a beehive, several hundred of the bees quickly form a compact ball around the hornet to stop it. They don't sting, bite, crush, or suffocate it. Rather they...

    How to find the final height of a moving object

    I'm using WileyPlus and its not taking any of the answers I have come up with. I inserted all the variables into this modified equation to find the final x variable: X=(V^2-V0^2+2aX0)/2a Did I do the algebra wrong? I keep getting 1.047m.

    Why is the square root of (v^2 + u^2) used in the equation for momentum?

    Homework Statement a) KE=(1/2)(m)(v-u)2 Conversion: u = (31km/hr)(1hr/3600s)(1000m/km) = 8.61m/s v = (64km/hr)(1hr/3600s)(1000m/km) = 17.78m/s KE = (1/2)(1850kg)(17.782-8.612) = The Answer for a) b)Momentum= m(√(v2+u2)), v=14.17i u=11.39j =...
