A football is kicked at ground level with a speed of 17.2 m/sm/s at an angle of 44.6 ∘∘ to the horizontal. Part A How much later does it hit the ground? Express your answer using three significant figures and include the appropriate units. tt =

how do i solve this problem

Help! An asteroid is heading towards us at 10 km/s. Scientists decide the best solution is to attach a rocket to the asteroid and fire it to change the trajectory of the asteroid. If the rocket is fired for 8 min, the scientists calculate that the new speed for the asteroid will be 21 km/s and its new trajectory will be at an angle of 25° to its original path. Part A In the process described above, what is the acceleration of the asteroid? Express your answers using two significant figures separated by a comma. Assume that the positive axis is in the direction of the initial motion of the asteroid. The final motion of the asteroid has components in the x and positive y directions only. ax ay = for Part A for Part A undo for Part A redo for Part A reset for Part A keyboard shortcuts for Part A help for Part A Review I Constants m/s2
