Questions
A ball is thrown from the top of 36 m high tower with velocity 5 m/s at an angle 37° above the horizontal as shown. Its horizontal distance on the ground is closest to : [g = 10m/s2]
detailed solution
Correct option is A
By using.s=ut+12at2 in vertical direction-36 = 3t - 5t2 =t = 3sRange = (5cos37°) t = (4). 3 = 12mTalk to our academic expert!
