Answer:
The acceleration of the ball as it moves down the grassy incline, if constant, is 5.1 m/s²
Explanation:
Initial velocity, u = 0m/s
Acceleration = ?
Vertical distance covered as at t=4.1s, H = 43m
Using the equations of motion,
H = ut + 0.5at²
43 = 0 + 0.5a (4.1)²
a = 43/(0.5×4.1²) = 5.1 m/s²
Hope this Helps!!
2. Explain Distance
3. Differentiate between distance and position.
Note : All these questions are under Physics.
Answer:
1-Simple harmonic motion, in physics, repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side. The time interval of each complete vibration is the same
2-Distance is a numerical measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). The distance from a point A to a point B is sometimes denoted as
3-Position is the location of the object (whether it's a person, a ball, or a particle) at a given moment in time. Displacement is the difference in the object's position from one time to another. Distance is the total amount the object has traveled in a certain period of time.
Explanation:

b. high frequency, short wavelength
c. low frequency, short wavelength
d. high frequency, long wavelength
Answer: B: High frequency, short wavelength
Explanation: Well, if its a higher frequency it carries more than a low frequency, and when its a short wavelength, it doesn't take up as much energy for it to move, so it makes it larger amounts of energy, hope this helps!
A body revolving in circle generally has tangential acceleration if the speed is changing. Since the speed is uniform here, the tangential acceleration is zero.
centripetal acceleration is directed towards the center and is given as
a = v²/r where a = centripetal acceleration , v = speed , r = radius
Since both speed and radius are constant here, the centripetal acceleration is constant and is always directed towards the center.
hence the correct choice is
The acceleration is directed toward the center.
