The height of a projectile that has been launched upward can be determined by finding the sum of the product of the object's acceleration and , the product of the object's initial velocity and t and the object's initial height , where t represents the number of seconds after the object has been launched . An object's acceleration can be assumed to be -32 ft / s , which is the acceleration due to gravity.
How long after launch will the projectile land on the ground? show your work
If the initial velocity stays the same , but the height the projectile is launched from changes , how would the amount of time change that it takes for the projectile to reach its maximum height ? How would its maximum height change ?
Assuming the velocity stays the same , at what height above the ground does the projectile need to be launched to increase the amount of time it will take for the projectile to return to the ground by one second?

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
