Describe an instance where you might use standard rounding. Describe an instance where you might use order of magnitude estimation. I need help on this plz! I’m running out of time. If you did this too plz help me out!

b. a lightning bug, plug of grass, and a worm

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
