Explanation:
Taking west to be positive, given:
v = 17.9 m/s
a = 63.7 m/s²
t = 0.21 s
Find: v₀
v = at + v₀
17.9 m/s = (63.7 m/s²) (0.21 s) + v₀
v₀ = 4.52 m/s
The initial velocity is 4.52 m/s west.
Answer:
9.74 x 10^7 m/s
Explanation:
V = 27000 V
energy of electrons = e x V
K = 1.6 x 10^-19 x 27000 = 43200 x 10^-19 J
Energy = 1/2 m v^2
43200 x 10^-19 = 0.5 x 9.1 x 10^-31 x v^2
v^2 = 9.495 x 10^15
v = 9.74 x 10^7 m/s
