I am already done except for 2.35 I dont know hot so solve it because it only have one given :'> plz help and I will study it

K' \"3 in 85%- (1st SW) Kinematic Equation Problem Sets \"Answer the following problems below. Please include your solutions." 2.10 - A physics professor leaves her house and walks along the sidewalk toward campus. After 5 min it starts to rain and she relums home. Her distance from her house as a function of time is shown in Fig. E2.l0. At which of the labeled points is her velocity [:1] zero?
