Anyone can be bitten or stung by an insect, and bites and stings are very common. Youâre at greater risk if you spend a lot of time outdoors, especially in rural or wooded locations. Children and older adults may have more severe reactions to bites and stings.
60 feet divided by this number should be the arrow's speed in feet per second. Double the distance from the masking tape to the center of the 40 yard grouping, and divide by 32 feet per second per second.20 feet divided by this number is the arrow's speed in feet per second, and should be the approximately same as the result in step 6, allowing for errors in measurement.
Take another derivative to find the acceleration. a(t) = v'(t) = 2j. Below is a picture of the vectors. Projectile Motion. Since the velocity and acceleration vectors are defined as first and second derivatives of the position vector, we can get back to the position vector by integrating. You can fire your anti-missile at 100 meters per second. At what angle should you fire it so that you intercept the missile.
