Explanation:
formula for force is:
force=mass × acceleration
but in case of friction
force =coefficient of friction × Normal Reaction
F. = u × R
U = F/R
but when placed horizontally
R= M×G
M=mass=60kg
G=Gravity(10m/s or 9.8m/s)
F=140N
U=140/60×10
U=140/600
U=0.2333333333
approximately to 3 significant figures
U=0.233
if i am correct rate it 5 star
Gravitational to Kinetic to Chemical
Answer:
Amplitude will be equal to 0.091 m
Explanation:
Given mass of the slits = 41 gram = 0.041 kg
Frequency f = 1.65 Hz
So angular frequency 
Angular frequency is equal to 

Squaring both side

k = 4.40 N/m
For vertical osculation


A = 0.091 m
So amplitude will be equal to 0.0391 m
Answer:
16.6N
Explanation:
Given parameters:
Mass of rocket = 2000g = 2kg
Acceleration = 8.3m/s²
Unknown:
Force acting on the rocket = ?
Solution:
The force acting on a body can be derived from the product of its mass and acceleration;
Force = mass x acceleration
Insert the parameters and solve;
Force = 2 x 8.3 = 16.6N
You must first convert minutes to seconds so 10*60=600
Then multiply the number of seconds by the speed so 600*2=1200 m
