Answer 1

Explanation:

m = 3 x 10⁷ kg 

F = 5 x 10⁴ N 

s = 3 m 

u = 0 

v = ? 

we know , 

F = ma 

5 x 10⁴ = 3 x 10⁷ x a 

5/3 x 10⁻³ = a 

1.6 x 10⁻³ = a 

we know 

v² = 2as + u²

v² = 2 x 1.6 x 10⁻³ x 3 + 0²

v² = 9.96 x 10⁻³ 

v = √ 9.96 x 10⁻³ 

v = 10⁻²(9.96 x 10)

v = 10⁻² x 9.97

v = 0.0997 m/s

Answer 2

Answer:

Refer the attachment!!

since the acceleration is very less acc to my calculations,, therefore the velocity is in opposite direction.

It may be incorrect, I'm not sure , if its incorrect then sorry.

THNKS!
