Answer:
52.5 m
Explanation:
The displacement is the area under the velocity vs time graph.
From 0 to 5 seconds, the area is the area of the triangle plus the area of the rectangle.
x = ½ (3 s) (15 m/s) + (2 s) (15 m/s)
x = 52.5 m
Answer:
A = 62.5 g
using half life formulas, plug in missing variables.
If you are not advised to evacuate or are unable to do so safely, stay indoors, away from windows, skylights and doors. Continue to monitor weather reports and do not go outside until the storm has passed. And, to protect your children from seeing too many sights and images of the hurricane, limit media exposure.
