2. In the near future, do you think deserts are likely to con-nue expanding or will deser-fica-on be contained or even reversed? Why?

Explanation:

Given

initial velocity of the ball u = 25m/s

acceleration a = 130m/s²

time t = 0.5secs

Required

Final velocity v

Using the equation of motion

v = u+at

Substitute the given values

v = 25 + 130(0.5)

v = 25 + 65

v = 90

Hence the final velocity if the implement and the ball made contact for 0.5 sec is 90m/s
