The longest bone in a human body is the Fumer (thigh bone)
The maximum height of the object when thrown at the speed of 20 m/s is 20 m.
What is speed?
Speed is the magnitude of the rate of change of the position of any object with time which is a scalar quantity. It is the ratio of speed by time with the unit m/s or cm/s.
The height this object can travel with initial speed of 20 m/s can be calculated as,
<u>v^2 = u^2 + 2as</u>
where v is the final velocity, u is the initial velocity a is the acceleration due to gravity s is height.
0 = 20^2 + 2 (-10) s
s = 400 / 20 = 20 m
Therefore, the maximum height the object can travel with initial speed of 20 m/s is 20m.

length × width × height
20 cm × 10 cm × 5 cm = 1,000 cm
Answer:
2.75 m/s^2
Explanation:
The airplane's acceleration on the runway was 2.75 m/s^2
We can find the acceleration by using the equation: a = (v-u)/t
where a is acceleration, v is final velocity, u is initial velocity, and t is time.
In this case, v is 71 m/s, u is 0 m/s, and t is 26.1 s Therefore: a = (71-0)/26.1
a = 2.75 m/s^2
