Answer:
The magnitude of momentum of the airplane is 
.
Explanation:
Given that,
Mass of the airplane, m = 3400 kg
Speed of the airplane, v = 450 miles per hour
Since, 1 mile per hour = 0.44704 m/s
v = 201.16 m/s
We need to find the magnitude of momentum of the airplane. It is given by the product of mas and velocity such that,
or
So, the magnitude of momentum of the airplane is . Hence, this is the required solution.
Most often those smaller structures are triangular in shape because triangular shapes are very strong and stable
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J
Answer:
Explanation:
14 lb force is required to stretch the spring by 4 inch distance
So we have
stretch in the spring is given as
now we will have
Now we need to find the work to stretch it by x = 10 in = 0.254 m
so we have
iron, cobalt and Nickel is the answer
