please solve I'll make BRAINLIST for sure its urgent kaushik​

Answer 1

Answer:

Hey mate! Here is ur answer...

Explanation:

mass(m) = 5kg

initial velocity (u) = 10m/s

time(t) = 25s

Final velocity(v) = 35m/s

(i)Momentum before applying force (P1) = mu

= 5×10

= 50m^2/s

(ii)Momentum after applying force (P2) = mv

= 5×35

= 175m^2/s

(iii) Gain in momentum per second,i.e., rate of change in momentum = mv-mu

= m(v-u)

= 5(35-10)

= 5×25

= 125m^2/s

(iv) Force(F) = ma

= m(v-u)/t

= 5(35-10)/25

= 5×25/25

= 5N
