Answer:
4500 N
Explanation:
F = ma
= 1500 kg * 3 m/s^2 = 4500 N

Answer:
s = 90 m
a = 56 m/s²
Explanation:
I will ASSUME that your equation is silly as it reduces to V = 11t which is constant, and that you mean V = 9t² + 2t
Position is the integral of differential velocities
s =
s = 3t³ + t² | from 0 to 3
s = 3(3)³ + 3² - (0) = 90 m
acceleration is the derivative of velocity
a = v' = 18t + 2
a(3) = 18(3) + 2 = 56 m/s²
Answer is C. Kelvin, Kelvin is the temperature scales does water boil at the highest numerical value. Hope it helped you, and have a great day.

Answer:
In these formulas, it is useful to understand which variables are parameters that specify the nature of the wave. The variables E₀ and B₀ are the amplitudes of the electric and magnetic fields.
Explanation:
Generally, the variables that specify the nature of the wave are:
(1) The amplitude of the electric field, designated as E₀, and
(2) The amplitude of the electric field, designated as B₀.
Answer:
8 m/s²
Explanation:
α = 0.04 rad/s²
w = 0.2 rad/s
t = ?
α = w/t
===> t = w/α = 0.2/0.04 = 5 sec
v = wr = 0.2 × 200 = 40 m/s
the net acceleration a = v/t = 40/5 = 8 m/s²
