What is the height a toy plane can reach that has a mass of 5 kg and is flying at a rate of 8 m/s straight upward? Assume all energy is conserved.

co2reflects heat radiation back to earth buning coal and oil emits co2 globe warms

the higher the current the higher the mag field around it the higher the influence on the compass

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
