Answer:
The extra force exerted against the bottom is 5880 N.
Explanation:
Given that,
Diameter of the bottle= 2.00 cm
Diameter of the jug = 14.0 cm
Force = 120 N
We need to calculate the extra force exerted against the bottom
Using formula of force
Put the value into the formula
Hence, The extra force exerted against the bottom is 5880 N.
Answer:
(a) Maximum height = 53.88 meters
(b) Range of the ball = 924.36 meters
Explanation:
The ball has been launched at a speed = 44.4 meters per second
Angle of the ball with the horizontal = 25°
Horizontal component of the speed of the ball = 44.4cos25° = 40.24 meters per second
Vertical component = 44.4sin25° = 18.76 meters per second
We know vertical component of the speed decides the height of the ball so by the law of motion,
v² = u² - 2gh
where v = velocity at the maximum height = 0
u = initial velocity = 18.76 meter per second
g = gravitational force = 9.8 meter per second²
Now we plug in the values in the given equation
0 = (18.76)² - 2(9.8)(h)
19.6h = 352.10
h =
h = 17.96 meters
By another equation,
Now we plug in the values again
18.76t = 4.9t²
18.76 = 4.9t
t = seconds
Since time t is the time to cover half of the range.
Therefore, time taken by the ball to cover the complete range = 2×3.83 = 7.66 seconds
So the range of the ball = Horizontal component of the velocity × time
= 40.24 × 7.66
= 308.12 meters
This we have calculated all for our planet.
Now we take other planet.
(a) Since the golfer drives the ball 3 times as far as he would have on earth then maximum height achieved by the ball = 17.96 × 3 = 53.88 meters
(b) Range of the ball = 3×308.12 = 924.36 meters
