Question

Suppose that an airplane flying 70 m/s at a height of 300 m drops a crate. What horizontal distance will the crate have traveled when it hits the ground? Assume negligible air resistance. O 21000 m O 548 m O 242 m O 61 m

Answer 1

Answer:

option B

Explanation:

given,

seed of airplane = 70 m/s

height = 300 m

we know,

$s = ut + \dfrac{1}{2}at^2$

$300 = 0 + \dfrac{1}{2} \times 9.81\times t^2$

t = 7.82 s                                  

now, the range of the crate

 R = V × t

     = 70 × 7.82                      

     = 547.44 ≅ 548 m                          

hence, the correct answer is option B
