Given,

Mass (m) = 0.59kg

Time (t) = 0.19sec

Speed (v) = 10m/sec

Force (F) = ?

We know that:-

Force (F) = Mass (m) x Acceleration (a)

Force (F) = 0.59kg x speed (v) / Time (t) = 0.59kg x 10m/sec / 0.19sec Force (F) = 0.59kg x 52.63m/sec² = 31.05kg.m/sec² ∴ Force (F) = 31.05N

use the newton second law of motion

F=ma

m=0.50kg

a=10/0.19

a=52.63

F=0.50*52.63

F=26.35N

F = m*a = m*ΔV/Δt = 0.59*10*100/19 = 31 N
