more deceleration.
in vertical motion downwards => terminal velocity ... raindrops etc
Answer/
I have no idea i’m so sorry
Explanation/
Have a good day
Explanation:
t = usin©/g
Where t is the time to reach the maximum height
Time spent in air is T = 2t
Hence, T = 2usin©/g
T = 2 x 20 x sin 65°/ 9.8
T = 3.69s
1m is equivalent to 100cm
1m = 100cm
Answer:
B) -1m/s^2
Explanation:
Final speed = 0 m/s
Initial speed = 5m/s
Time taken for it to come to rest(0m/s) = 5
then use the formula;
[v = u + at],where v is the final speed..u is the initial speed..t is time taken for it to come to rest and a is the acceleration
; 0 = 5 + 5a
; -5 = 5a
;Acceleration = -1 m/s^2
