is to the nearest integer]
a) 30 m sec
b) 42 m/sec
c) 32 m/sec
d) 35 m/sec
​

Answer 1

Answer:

c) 32 m/sec

Explanation:

For maximum range, R=gu2sin2θ

For maximum horizontal distance, θ should be 45o

Therefore, 100=gu2Sin9001000=u2

  (Considering g= 10 m/s2)

u= 1010 m/s

Answer 2

Answer:

c) 32 m/sec is correct answer.
