Explanation:
The kinetic energy of an object is given in terms of its mass and object as :
An object with more mass has more kinetic energy. An object with less mass, if both objects are moving at the same speed, in opposite directions, will have less kinetic energy. The square of v will give positive number.
Answer:
1.52g
Explanation:
Given parameters:
Force = 125N
Mass combined = 82kg
Unknown:
Acceleration of the bicycle = ?
Solution:
From Newton second law of motion suggests that:
Force = mass x acceleration
Acceleration = = = 1.52g
<em>Note: Your question inputs seem a little odd. But, I am assuming that you really mean '10km in 5 ms'.</em>

Answer:
The Average speed = 15000 / 0.005 = 3000000 m/s
Explanation:
- Average speed can be calculated by dividing the total distance covered by the total time.
Average speed = Total Distance / Total time
Given
- Total distance = 15km = 15(1000) = 15000 m
- Total time = 5 ms = 0.005 seconds
Thus,
Average speed = Total Distance / Total time
Average speed = 15000 / 0.005 = 3000000 m/s
Answer:
1.37 ×10^-3 T
Explanation:
From;
B= μnI
μ = 4π x 10-7 N/A2
n= number of turns /length of wire = 1700/0.75 = 2266.67
I= 0.48 A
Hence;
B= 4π x 10^-7 × 2266.67 ×0.48
B= 1.37 ×10^-3 T
KE= 0.5(m)(v^2)
KE= 250,000 J
