The trajectory of these seeds can be determined with a high-speed camera In an ex 20 cm above ground level with initial speeds between 2 3 m/s and 46 m/s. The launch angle is measured from the horizontal, with+90 corresponding to an initial velocity straight up and-90 straight down If a seed is launched at an angle of 0° with the maximum initial speed, how far f ground is flat on one type of plant, seeds are projected at 20 cm 93 cm 22 m 4 6 m

Explanation / Answer

From

Y=Yo+Voyt+(1/2)gt2

0.2=0+0+(1/2)*9.81*t2

t=0.202 s

Horizontal distance travelled

X=Voxt =4.6*0.0202

X=0.929 m =93 cm (approx)
