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:
<h3>An object which moves in the negative direction has a negative velocity</h3><h3>If the object is slowing down then its acceleration vector is directed in the opposite direction as </h3><h3>its motion</h3>
Answer:
Explanation:
The cross section area of the cable is
Let g = 9.81m/s2. The stress acting on the cable when mass is added is
The strain when the cable is stretched from 4.76 to 5.43 m is
So the young modulus of the cable is
Answer:
Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields. Lava can kill plants and animals too.
