A : 10000 J
B: 625 J
C: 2500 J
Step-by-step explanation:
Step 1:
We know that ,
Kinetic Energy is given by ((1/2) × m × V²) J
where m = Mass of substance
V = Velocity
Step 2:
In first case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 20 ×20
= 10000 J
In second case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 5 ×5
= 625 J
In Third case, m= 50 kg, V=10 m/s
Kinetic energy = 0.5 × 50 × 10 ×10
= 2500 J

Answer:
3848.45mm
Step-by-step explanation:
Area = 
= 1225
1225 * 
= 3848.45
Amount - A, Rate - r, Principal - P, Interest - I, Time - t
Explanation:
- Accrued amount (Amount in the account) is represented by the first letter in amount "A".
- Interest rate (as a decimal) is represented by the first letter in rate "r".
- Principal (amount you start with) is represented by the first letter in Principal "P".
- Interest earned (in dollars) is represented by the first letter in interest "I".
- Time (calculated in years) is represented by the first letter in time "t".
