need help guys. plz ​

Answer 1

Answer:

in the second case the block will move and it will move in the right direction

Answer 2

Answer:

1) The second A block will move in the right direction as more force is being applied at the right direction i.e 35

Explanation:

2)

Given :

Initial Velocity = 0(as it started from rest)

Final Velocity=72km/hr i.e 20 m/s

Time = 5min i.e 5*60 = 300 sec

Solution:

i) by using the 1st equation in of motion I.e.

v=u+at

20=0+a*300

20=300a

a= 20/300

a= 1/15 m/s

a = 0.66m/s

ii) by using the second equation of motion i.e

V^2= U^2+ 2aS

20^2= 0^2+ 2* 0.66* S

400= 2*0.66S

400/2=0.66S

200=0.66S

S=0.66/200

S= 0.033 m
