Question

from the top of 11 m high tower a stone is projected with speed 10 m/s at an angle of 37 degree find
​time of flight

Answer 1

Answer:

t=1

Explanation:

h = 11 m;

h = 11 m;usinQ = 10*3/5= 6ms-1

h = 11 m;usinQ = 10*3/5= 6ms-1s= ut+1/2at²

h = 11 m;usinQ = 10*3/5= 6ms-1s= ut+1/2at²11= 6*t+1/2*10*t²

h = 11 m;usinQ = 10*3/5= 6ms-1s= ut+1/2at²11= 6*t+1/2*10*t²11= 6t+5t²

h = 11 m;usinQ = 10*3/5= 6ms-1s= ut+1/2at²11= 6*t+1/2*10*t²11= 6t+5t²5t²+6t-11=0

h = 11 m;usinQ = 10*3/5= 6ms-1s= ut+1/2at²11= 6*t+1/2*10*t²11= 6t+5t²5t²+6t-11=05t²-5t+11t-11

h = 11 m;usinQ = 10*3/5= 6ms-1s= ut+1/2at²11= 6*t+1/2*10*t²11= 6t+5t²5t²+6t-11=05t²-5t+11t-115t(t-1)-11(t-1)

h = 11 m;usinQ = 10*3/5= 6ms-1s= ut+1/2at²11= 6*t+1/2*10*t²11= 6t+5t²5t²+6t-11=05t²-5t+11t-115t(t-1)-11(t-1)t=1;
