Answer:
Vtennis = 134 [cm^3]; Vgolf = 40.76 [cm^3]
Explanation:
To solve this problem we must have the values of the radius or diameters of each of these balls, therefore performing an internet search we can appreciate that the diameters of these balls are:
Dt = 6.35[cm]
Dg = 4.27[cm]
But we need the radius, and we know that the radius is equal to the half of the diameter.
Rt = 3.175 [cm]
Rg = 2.135 [cm]
Now replacing this values in the given equation:
Answer:
v = 1.7 m/s
Explanation:
Given that,
Initial velocity of the object, u = 1 m/s
Acceleration of the object, a = 1 m/s²
We need to find the velocity of the object after moving 1 m. Let v be the velocity. Using third equation of kinematics to find it i.e.
So, the final velocity of the object is 1.7 m/s.
