'Tension In A String'-type problem.....!!

Dear student

 

Let the upward acceleration be 'a'.

The tension in the string,

T = m ( g + a )

 

here, T = 48000N , m = 4000kg, g= 9.8 m/s² ;

By putting these values in the given eqn, the value of upward acceleration can be calculated

 

Once the value of 'a' is found out , the following eqn can be used to calculate the distance traveled in 3s

 

s = ut + ( 1/2 ) at²
