Question
From top of a tower 160 m high a body is projected upwards with a velocity of 40 m/s making an angle of 30° with the horizontal. Find the time it will take to reach the ground
Answers
Steve
initial upward speed is 20 m/s
h(t) = 160 + 20t - 4.9t^2
when is h=0?
h(t) = 160 + 20t - 4.9t^2
when is h=0?
