It will take a total of 15 minutes i believe. t = d/r
t = 5mi/20mph = .25hr
60 min = 1 hr
.25*60 min = 15 minutes it wil take him
Answer:
Explanation:
let the velocity of throw is u .
Time to reach horizontally .25 m is equal to reach .45 m vertically
t = .25 / u cos63
= .55 / u
For vertical motion
- h = - ut + 1/2 gt²
-.45 = -usin63 x .55 / u + .5 x9.8 (.55 / u )²
-.45 = - .49 + 1.48 / u²
.04 = 1.48 / u²
u² = 37
u = 6.08 m /s
Answer:
Explanation:
standard decimal form of 6.36*10^4 is
