Answer:
a. 18.13m/s
b. 0.84m
c. 2.4m
Explanation:
a. to find the speed at which the ball was lunched, we use the horizontal component.Since the point distance from the base of the ball is 24m and it takes 2.20 secs to reach the wall,we can say that
t=distance /speed
Hence the speed at which ball was lunched is 18.13m/s
b. from the equation
the vertical distance at which the ball clears the wall is
y=8.14-7.3=0.84m
c. the time it takes the ball to reach the 6.2m vertically
the horizontal distance covered at this speed is
B) Energy from the sun is the answer, I am sure;
The water cycle is driven primarily by the energy from the sun<span>. This </span>solar energy<span> drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.</span>
