Answer:
i) 0.7
ii) 1.39
iii) 0.6
Next time, when compiling a Physics question, ensure you put the unit of each measurement.
Explanation:
i) T = time of flight = [tex]\frac{2uSin(A)}{g}[/tex]
where u = speed = 4, A = 60 and g = acceleration due to gravity = 10 (It is a constant);
Subsituting the values, we have: T = [tex]\frac{2(4)Sin(60)}{10}[/tex] = 0.7
ii) distance travel = Range = R = [tex]\frac{u^{2}Sin(2A) }{g}[/tex]
where u = speed = 4, A = 60 and g = acceleration due to gravity = 10 (It is a constant);
Subsituting values, we have: R = [tex]\frac{4^{2}Sin(2*60) }{10}[/tex] = 1.39
iii) Maximum Height = H = [tex]\frac{u^{2}(Sin(A))^{2} }{2g}[/tex]
where u = speed = 4, A = 60 and g = acceleration due to gravity = 10 (It is a constant);
Subsituting values, we have: [tex]\frac{4^{2}(Sin60)^{2} }{2*10}[/tex] = 0.6
