Answer:
3.7 N/kg
Explanation:
The gravitational strength refers to the amount of gravity acting per unit mass. Hence in this case,
Gravitational Strength = Weight / Mass
= 370 / 100

Answer:
The centripetal acceleration of the runner is 
.
Explanation:
Given that,
A runner completes the 200 m dash in 24.0 s and runs at constant speed throughout the race. We need to find the centripetal acceleration as he runs the curved portion of the track. We know that the centripetal acceleration is given by :
v is the velocity of runner
Centripetal acceleration,
So, the centripetal acceleration of the runner is . Hence, this is the required solution.
Trial and error
scientific laws and theories are proven by experimental data and large bodies of evidence.
