The time of motion of the object at the given speed and distance is 4 seconds.
<h3>Time of motion of the object</h3>
The time of motion of the object is calculated as follows;
t = d/v
where;
- d is distance = 10 m
- v is speed = 2.5 m/s
- t is time of motion
t = 10/2.5
t = 4 s
Thus, the time of motion of the object at the given speed and distance is 4 seconds.

Answer:
If the height is in metres, the speed is 24.25m/s
Answer:
"12.4 g/mL" would be the right solution.
Explanation:
The given values are:
Mass of the object,
= 149.8 g
Volume of the object,
= 12.1 mL
Now,
The Density will be:
⇒ 
On substituting the given values in the above formula, we get
⇒ 
⇒ 
From newtons second law of motion,
F=ma hence,
F=20N
m=5kg so,
20=5×a
a=4m/s^2
