Answer:
25kJ
Explanation:
K = 1/2 mv^2 = 1/2 x 2000kg x (5.0m/s)^2
= 25 x 10^3 J = 25kJ
#1). neutrons
#2). atomic number
A. 500 N
Acceleration is change in velocity over change in time.
a = Δv / Δt
a = (50 m/s − 20 m/s) / 3 s
a = 10 m/s²
Force is mass times acceleration.
F = ma
F = (50 kg) (10 m/s²)
F = 500 N
