Acable is lifting a construction worker and a crate, as the drawing shows. the weights of the worker and crate are 965 n and 1510 n, respectively. the acceleration of the cable is 0.620 m/s2, upward. what is the tension in the cable(a) below the worker and(b) above the worker?

(a)2631.46 N

(b)1605.51 N

Explanation:

Assuming there is a cable between crate and worker

Given

weight of worker

Weight of crate

mass of worker

mass of crate

acceleration of system

Tension in the wire carrying Worker

(b)Tension in the string above

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
