Answer:
Explanation:
Option C is the correct answer
Answer:
3m/s
Explanation:
Given parameters:
Initial speed = 2m/s
Acceleration = 0.5m/s²
Time = 2s
Unknown:
Final speed = ?
Solution:
To solve this problem, we apply the right motion equation;
V = U + at
V is the final speed
U is the initial speed
a is the acceleration
t is the time
V = 2 + (2 x 0.5)
V = 2 + 1
V = 3m/s
The correct answer is 9.45 kg.
The formula for calculating the density of an object is expressed as:
Density = mass / volume
Given :
Density = 150kg/m³
Volume of the sphere = negligible
r is the radius = 50/2 = 25cm = 0.25m
We can find the volume of the Styrofoam sphere by
=(4/3)πr³
Volume (V) = (4/3)*π*(0.25)³
Volume = 0.063 cm³
Now let us find the required mass:
Mass = density * volume
Mass = 150 * 0.063
Mass = 9.45 kg
Therefore, the maximum mass that can hang without sinking from a 50.0 cm -diameter Styrofoam sphere in water is 9.45 kg.
