it's def. TRUE. i got the same question and i got it right
Answer:
increasing; speeding up is my answer
Answer:
11.78meters
Explanation:
Given data
Mass m = 100kg
Length of cord= 10m
Spring constant k= 35N/m
At the greatest vertical distance, the spring potential energy is equal to the gravitational potential energy
That is
Us=Ug
Us= 1/2kx^2
Ug= mgh
1/2kx^2= mgh
0.5*35*10^2= 100*9.81*h
0.5*35*100=981h
1750=981h
h= 1750/981
h= 1.78
Hence the bungee jumper will reach 1.78+10= 11.78meters below the surface of the bridge
The rocket engine works on the basic principle proposed by Newton which is Newton’s Third Law.
Momentum = (mass) x (speed) = (1 kg) x (0.01 m/s) = 0.01 kg-m/s
