Question

A ball is thrown upward with an initial velocity of 14 m/s. At what time does the ball reach the high point in its flight? (Use the approximate value of g = 10 m/s2 and remember that the velocity is equal to zero at the high point.)

Answer 1

v=v₀-gt
v=0
t=v₀/g=14/10=1.4 s

Answer 2

apply formula
v=u-gt
v=0
u=14
g=10
then t=1.4s
