In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the x axis. Use trigonometry to find the x and y components of the vector. Express your answer as a comma-separated pair of components. 1. 50.0N at 45.0 degrees
2. 65.0 m/s at 5pi/6 rad
3. 258lb at 340 degrees
4. 73.0km at 1.10 pi rad

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

ill do it for 100, also this isnt 80 its 40

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

find the sum of the two horizontal vectors and the sum of the two vertical vectors
