A football is kicked with an initial velocity of 25 m/s at an angle of 45 degrees with the horizontal . Determine the time of flight, the horizontal distance, and the peak height of the long jumper.
Get the time of flight from the initial vertical velocity component. The times spent going up and down are equal.
Range is horizontal velocity component times time of flight.
Peak height is achieved when the vertical velocity component is zero.
Now go earn some honors.
