Answer:
1.89 seconds
Explanation:
t = Time taken
u = Initial velocity = 9.6 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
Time taken to reach maximum height is 0.97 seconds
So, the stone would travel 4.7 m up
So, total height ball would fall is 4.7+12.8 = 17.5 m
Time taken by the stone to travel 17.5 m is 1.89 seconds
81 joule is the kinetic energy of the golf ball.
K.E= mv²/2
K.E=0.045×60×60÷2
K.E=81 joule
Kinetic energy is a particular kind of power that is present in moving particles or objects. An object gains kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force. Kinetic energy is a property of motion that depends on the mass and speed of an object or particle. Motion is any combination of vibration, axis rotation, translation, and movement (along a path from one location to another). A body's translational kinetic energy, which is determined by multiplying its mass, m, by the square of its speed, v, is equal to 1/2mv2.

Answer:
Acceleration will be change at every instant of time
Explanation:
We have given that speed of the car at curve round is constant
We know that speed is scalier quantity which does nit depend on the direction of motion.
Velocity is vector quantity which depends on the direction of motion
As on curve round direction of motion is always changes so velocity is also changes and acceleration is rate of change of velocity
So acceleration of the car will also change.

Your options are:
A) It is located at a distance of 2.6 million light years from Earth.
B) It has to travel a distance of 2.6 million kilometers to reach Earth.
C) It can be photographed by a space telescope in 2.6 million years.
<span>D) It has to move at the rate of 2.6 million kilometers per hour to reach Earth
You need to remember the definition of lightyear: one lightyear is the distance that light can travel in one year through space. It is a measure of astronomical distances and it is equal to 9.5×10¹²km.
Therefore, if light takes 2.6 million years to reach Earth, it means that the Andromeda Galaxy is at a distance of 2.6 million lightyears from Earth.
Hence, the correct answer is A) </span><span>It is located at a distance of 2.6 million light years from Earth.</span>
