An object is projected with a velocity of 100m-1
An object is projected with a velocity of 100m-1 at an angle of 60° to the vertical. Calculate the time taken by the object to reach the highest point (Take g as 10ms-2
5.0s
8.7s
10.0s
17.3s
20.0s
Correct answer is B
t = T2=12=2usinθg=100×sin6010
10 sin60 = 10 x 0.8660
= 8.7
