Answer:
14.8 m
Explanation:
S= ut + a
where u = initial velocity
S= (0 )(2) + (7.4)(2)
S= (7.4)(2)
S=14.8 m
Hi there!
I believe it looks like this.
At positions A, G kinetic energy is maximum.
At position D, potential energy is maximum.
Hope this helps! ☺♥
Answer:
Slower
Explanation:
Slower because the air would be pushing you back, and the other person would be walking faster because they are being pushed forward by the wind
The average speed is 116.66m/s.
Given - The path traced is 14km , time for jogging is 2 hrs=120min
To find the average speed-
- Speed refers to the ease of the movement and degree of mobility as a result of force application.
- Due to this there is involvement of velocity.
- Journey of average speed is the cumulative of distances and time.
- Kinetic theory refers to the Boltzmann constant connecting to the standards of distance traversed.
calculations-
Speed= 14 000 / 120
= 116.66m/s

Answer:
v = 54 m/s
Explanation:
Given,
The maximum height of the flight of golf ball, h = 150 m
The velocity at height h, u = 0
The velocity of the golf ball right before it hits the ground, v = ?
Using the III equations of motion
<em> v² = u² + 2gh</em>
Substituting the given values in the above equation,
v² = 0 + 2 x 9.8 x 150 m
= 2940
v = 54 m/s
Hence, the speed of the golf ball right before it hits the ground, v = 54 m/s
