Juggles the clown stands on one end of a teeter-totter at rest on the ground. bangles the clown jumps off a platform 2.2 m above the ground and lands on the other end of the teeter-totter, launching juggles into the air. juggles rises to a height of 3.8 m above the ground, at which point he has the same amount of gravitational potential energy as bangles had before he jumped, assuming both potential energies are measured using the ground as the reference level. bangles' mass is 70 kg. what is juggles' mass?

40.53 kg

Explanation:

Juggles 's mass = Mj

Bangles 's mass = 70 kg

Potential Energy is the Energy that an object gets due to its height of location

Potential Energy = mass * gravitational acceleration * height

Juggeles' s  Potential Energy = Bangles potential energy

                 Mj * g * 3.8  = 70 * g * 2.2

                                Mj = 40.53 kg

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
