    Calculating Work Done by Upward Buoyant Force on Hot Air Balloon

    Homework Statement A hot air balloon of mass 425 kg ascends from the ground level and accelerates at a rate of 1.25 m/s/s for 25 seconds. How much work is done by the upward buoyant force on the balloon? (conceptual) A certain amount of work W is required to accelerate a car from rest to a...

    Egg Throw Physics: Protecting the Egg During a Building Drop

    I misread the guidelines. The egg does not necessarily have to be visible. However curious3141, I'm not sure if I would like to slow it's descent down, as I would like to make the egg travel a farther distance also. But a parachute type contraption could work

    Egg Throw Physics: Protecting the Egg During a Building Drop

    Theoretically I could just wrap it in a ton of bubble wrap, but I would also have to explain it in the write-up qualitatively

    Egg Throw Physics: Protecting the Egg During a Building Drop

    My teacher is having us do an Egg Throw off of a building at our school. Further the distance, the more points we score on our grade. The project is pass/fail, if the egg breaks we get a 0. However, 60% of the actual project is a write-up explaining the concepts that happen to the egg as it is...

    Calculate the kinetic energy of the mass

    The acceleration I believe would be Fnet=ma (in the x direction). So add up all the forces in the X direction, which seems to be only one because the surface is frictionless. So mgsin30=5a
