So in calculating this one its is really hard to explain how i get it on solve it but you must consider this factors that i give in getting the answer. First is the distance cover by the ball when it is hit by the club, Second is you must estimate both of those data when it is in the moon and in the earth whre the gravity of the earth is 9.8m/s^2 so by calculating the Gravity of the moon or gMoon is equal 1.74m/s^2
Answer:
There is at least one instant which instantaneous acceleration is equal to average acceleration. 
.
Explanation:
The average acceleration experimented by the car is:
According to the Rolle's Theorem, there is at least one instant t so that instantaneous acceleration equal to average acceleration for the analyzed interval. That is to say:
If car is accelerating at constant rate, instantaneous acceleration coincides with average acceleration for all instant t. Then, instantaneous acceleration is:
Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. So if the Sun spontaneously lost half its mass (gasp, shudder, the horror!) then its gravitational pull on Earth would lessen as well, ultimately changing the very nature of our orbit around the Sun.
Thank You!

Answer:
The average speed will be 1.5km/hr .
Explanation:
Distance need to be traveled = 7.5Km
Time taken = 5 hours
Average speed refers to total distance traveled with respect to total time taken .
It can be calculated as given below :
Average speed =total distance /total time taken
Substituting the values we get ,as shown below
Average speed =7.5/5=75/50
Average speed = 1.5 Km/hr
Answer:
In a straight line
