Answer 1

Explanation:

Q2 MOMENTUM =MASS*VELOCITY

     175=35*V

      V=175/35

       V=5

Q3 F=10 N

      M=2.5KG

      U=3M/S

       V=7M/S

       T=?

        F=Ma

         10=2.5a

           a=4

         a =(V-U)/T

           a=(7-3)/T

            4=4/T

             T=1

Answer 2

Q.2)

Momentum = mass x velocity

175 = 35 × v

v = 175 / 35

v = 5 m/s

Q.3)

Force - F = 10 N

Mass - M = 2.5 kg

Initial velocity - U = 3 m/s

Final velocity - V = 7 m/s

Time - t = ??

F = M × a

10 = 2.5 × a

a = 10/2.5

a = 4

a = (V-U) / t

4 = (7-3) / t

4 = 4 / t

t = 4 / 4

Therefore,

t = 1
