Answer:
a. 27 m/s2
b. 2.75:1
Explanation:
a.
Since it is assumed that the race car starts from rest, initial velocity, u = 0 m/s
At the end of 402 m, distance, s = 402 m; and
Final velocity, v = 330 m/h
Converting this to m/s,
m/s
Using the equation of motion
b.
If acceleration due to gravity is taken as 9.8 m/s2, then
I\B
2/A
3\C
4\E
5\D
6\F
I think this is right

3 significant figures are in 1.02m
Explanation:
Answer:
5.5 x 10^5 N/C
Explanation:
t = 0.001 s
Δp = - 8.8 x 10^-17 kg m /s
Force is equal to the rate of change of momentum.
F = Δp / Δt
F = (8.8 x 10^-17) / 0.001 = 8.8 x 10^-14 N
q = 1.6 x 10^-19 C
Electric field, E = F / q = (8.8 x 10^-14) / (1.6 x 10^-19)
E = 5.5 x 10^5 N/C
