Abaseball player hits a ball at an angle of 52 degree and at a height of 4.8 ft. if the ball's initial velocity after being hit is 150 ft./s and if no one catches the ball, when will it hit the ground? remember that the acceleration due to gravity is 32 ft./s^2 a. 5.77 seconds b. 5.82 seconds c. 7.43 seconds d. 7.39 seconds

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
