Answer 1

Answer:

Hey mate here is your answer

6. Given,

Force = 10N

Mass = 2kg

Time = 3sec

To find:-

(i) Velocity of the body,

By applying, a = f/m

= 10/2

= 5m/s^2.

By applying, v - u = at

v - 0 = 5×3

v = 15m/s.

(ii) momentum of the body,

By applying, P = mv

= 2×15

= 30kg.m/s.

7.Given:-

Mass = 200kg

Time = 10sec

Distance = 100m

To find:-

(i) Velocity of the body,

By applying, v - u = at

V - 0 = 2×10

V = 20m/s.

(ii) Accleration of the body,

By applying, S = ut+1/2at^2

100 = 0×10 + 1/2×a×100

100 = 0 + 50a

a = 100/50

a = 2m/s^2.

(iii) Magnitude of the force,

By applying, F = ma

= 200×2

= 400N.
