1. 2+0.5+2.5= 3. 2km/hr average
2. 14-6=4seconds. 8m/s in 4s = 2m/s acceleration
3. 15m/s divided by 2.5 = 6m/s acceleration
Answer:
Electric Potential V=130 V
Explanation:
Electrical potential inside a hollow sphere is constant and is equal to electric potential of surface
So
Electric Potential V=130 V
Given data:
* The acceleration of the runner is,
* The initial velocity of the runner is,
* The time given is,
Solution:
By the kinematics equation, the final velocity of the runner is,
where v is the final velocity,
Substituting the known values,
Thus, the final velocity of the runner is 30.67 m/s.
