1.	A football is projected at an angle of 45° from the ground with an initial velocity of 10 m/s, take acceleration due to gravity is g = 10 m/s^2.What is the time of flight?(a) 1.4142 s(b) 1.5361 s(c) 1.8987 s(d) 1.5651 sThe question was posed to me in a job interview.The question is from Simple Projectile Motion topic in portion Motion in a Plane of Physics – Class 11
Answer» Right option is (a) 1.4142 s Explanation: The formula for TIME of FLIGHT is t = 2(V sinθ/g). Here, v = 10,θ = 45°, g = 10. HENCE, on solving we will GET the time of flight as 1.4142 s.
