This depends on what units you need to convert to, but the answer would be approximately 2.083 m/s.
5km/40min = 5000m/40min = 5000m/2400s = 2.083 m/s
Answer:
80 km/h
Explanation:
The answer is 160/2=80, the answer is 80km/h.
Answer:
Acceleration,
Explanation:
Given that,
Height from a ball falls the ground, h = 17.3 m
It is in contact with the ground for 24.0 ms before stopping.
We need to find the average acceleration the ball during the time it is in contact with the ground.
Firstly, find the velocity when it reached the ground. So,
u = initial velocity=0 m/s
a = acceleration=g
It is in negative direction, u = -18.41 m/s
Let a is average acceleration of the ball. Consider, v = and u = -18.41 m/s.
So, the average acceleration of the ball during the time it is in contact is .
I'm pretty sure it's 8, I could be wrong though
Answer:
When the electric force between two charged objects change, the distance between the objects increases in Iicreasing the separation distance between objects and decreases the force of attraction or repulsion between objects.
Hope it helps.
