His displacement is 0 .hope this helps :)
Answer:
They fell at the same time.
Explanation:
Galileo was the first to discover the property of gravity, in which it makes everything fall at the same time in an airtight space. Gravity makes all objects fall and accelerate at 9.8m/s/s, regardless of weight, because the ratio between the weight of the object and the air resistance acting against it is a constant.
Distance= Speed x Time Distance= 1.9m/s x 3.5h= 6.5km
I think this is right and I hope this helped you! :)
2 m/s² is the acceleration.
<u>Explanation:</u>
Acceleration is defined as the rate of change in velocity with respect to time.
Here the initial velocity, u = 4 m/s
the final velocity , v = 12 m/s
time = 4 seconds
Acceleration =
Plug in the values, we will get,
Acceleration =
= = 2 m/s²
Answer:
Increasing the number of trials reduces the impact of any one imprecise measurement. … To increase the number of attempts, you can find an average result for the experiment, as well as find and discrepancies as human error if you perform an experiment several times.
Explanation:
hope it helps :)
