Answer:
15009
Explanation:
PE = mgh
PE = 61.2(9.81)(10 * 2.50)
PE = 15009.3
Rise over run at 1 second
It’s the same slope from 0 to 2 seconds
10/2=5mps
As a note all time points between 0and 2 will have this instantaneous velocity
Instantaneous velocity at time 2 is 0
Answer:
5.619×10⁶ N
Explanation:
Applying,
F = kqq'/r²................... Equation 1
Where F = electrostatic force between the charges, k = coulomb's constant, q = first charge, q' = second charge, r = distance btween the charges
From the questiion,
Given: q = 2.5 C, q' = 2.5 C, r = 100 m
Constant: 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = (2.5×2.5×8.99×10⁹)/100²
F = 56.19×10⁵
F = 5.619×10⁶ N
The speed of the ball is 27.4 m/s
Explanation:
The speed of an object is given by:

where
d is the distance covered
t is the time taken
In this problem, we have:
d = 300 yards is the distance covered by the golf ball
t = 10 s is the time taken
Keeping in mind that
1 yard = 0.914 m
We can convert the distance from yards to meters:

And substituting into the equation, we find the speed of the ball:
