The answer is C because if it’s moving with a constant speed it’s gonna be balanced and there will be no force
Distance is 90km,time 1 hr
distance 2 is 82km,time 5 hrs
average speed=total distance travelled/total time taken.
90+82=172/5+1=6
average speed=28.7km over hour
Answer:
meter per second square
Explanation:
Given
Height ,h
m
Radius, r
m
Distance travelled,
m
Since, the stone is released and it falls towards the sky, its initial velocity is zero
As per equation
, we will evaluate "t"
Substituting the given values in above equation, we get

Velocity

centripetal acceleration
