Answers
Answer:-
H = 8.43 m
R = 19.48 m
T = 2.59 s
Given :-
To find :-
The height, range and time of flight.
Solution:-
Since, the body is projected with an angle of 60° from horizontal.
The maximum height covered by the football is :-
- Put the given values,
→
→
→
→
→
→
Now,
Range of the football will be :-
→
→
→
→
hence,
Range of football is 19.48 m
Time of flight of football :-
→
→
→
→
hence,
Time of flight will be 2.59s.
Height = 8.43 m
Range = 19.48 m
Time of the flight = 2.59 s
Given that :
To find :
Height, range and time of flight.
Solution :
The body is projected by an angle of 60° from horizontal.
We know that :
The maximum height covered by the football :
★
Plug the given values in equation :
Hence,
It implies that Height of the flight is 8.43.
We know that,
Range of the football will be :
★
Put the given values :
Hence,
It implies that the Range of football is 19.48 m.
We know that,
Time of flight of football :
★
Put the given values :
Hence,
It implies that the Time of flight will be 2.59s.
