An electron in a magnetic field moves along a circle with a radius of 40.4 m with a speed that follows: v(t) = v0 e^-bt
where b = 0.73 s^-1 and v0= 445 m/s.
What is the angular acceleration at t= 3s?

what was the answer?

show the wavelengths of a wave. show the crests of a wave.

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
