A girl tries to jump over a 0.825 m
wide creek by jumping at 3.87 m/s
at a 18.8° angle. What is her
height when she reaches the
other side of the creek?
3.87 m/s)*sin (18.8 degree) = 1.247 m/s. That’s the vertical component of her initial velocity. The horizontal component is 3.864 m/s. It takes(0.825m/s)= 0.225 seconds for her to cross the creek. Height = 0.0325 meters
