Answer:
The magnitude of the force is 0.4 N.
Explanation:Given:
Mass of the particle m=200g
Displacement of the particle s=400cm
Initial velocity of the particle u=0m/s
Time taken t=2s
Solution:Step 1:
To convert displacement from cm to m
s=400/100=4m
Step 2:
Using Newton's second law of motion,
[tex]s = ut + 1 \div 2at {}^{2} [/tex]
s- displacement of the particle
u- initial velocity of the particle
a- acceleration of the particle
t-time taken
By substituting value in the above equation ,we get
4=0×2+1/2a×2×2
a=4/2
a=2m/s^2
step 3:We convert mass from g to kg
m=200/1000=0.2kg
step 4:using second law of motion
F= m×a=0.2×2
F=0.4N
Force:- Force is a push or pull .It depends on mass and acceleration of the body.
