A body is projected at angle 45 0 to horizontal with velocity 20 m/s from ground. If there is an acceleration in horizontal direction of 2 m/s 2 , then calculate horizontal range of this particle-
Text Solution
Verified by ExpertsThe correct answer is:
B
Time of flight does not depend on horizontal acceleration
∴ T = 
= 
= 
s
R = u x T + 
a x T 2
= (20. cos 45º) ( 
) + 
(2) ( 
) 2
= 40 + 8 = 48 m
