Work done by force is given by formula
now here work done against friction is given so force of friction here is
It moved by three corridors with each measures
so total distance will be
now from above formula of work done we will say
so above is the work done to move three corridors
Answer:
The value of tension on the cable T = 1065.6 N
Explanation:
Mass = 888 kg
Initial velocity ( u )= 0.8
Final velocity ( V ) = 0
Distance traveled before come to rest = 0.2667 m
Now use third law of motion =
- 2 a s
Put all the values in above formula we get,
⇒ 0 = - 2 × a ×0.2667
⇒ a = 1.2
This is the deceleration of the box.
Tension in the cable is given by T = F = m × a
Put all the values in above formula we get,
T = 888 × 1.2
T = 1065.6 N
This is the value of tension on the cable.
Answer:
1 m/
Explanation:
The Net Force refers to the sum of all forces acting on an object. Hence,
Net Force of box
= 20 + (-9.0) [It is -9.0 as both forces are in different directions]
= 11.0 N
We also need to know that the net force on an object is equal to the product of the mass of the object and the acceleration of the object. Hence,
11.0 = 12.0
= 1 m/
