Question

answer all the problems​

Answer 1

13) Mg/5

14) in this question use 1/2 kx^2 =mgx

2mg/k = x

15) in. This question use F = (v/t)^2/A

Answer will be 10 N

16) (sin theta) ^1/2

17) we know T = 2m1m2(g +a') /m1+m2

In this question

a = g

So T = 4m1m1g/m1+m2

18) in this question

4g = N + T

T = 2g

N = 4g - 2g =20 N

19)use F. t = m(v2-v1)

Amswer will be 12.6

20) f = mgsin30

=mgsin30

= mg/2
