Two forces act on a 6.00- kg object. One of the forces is
Stella [2.4K]

Answer:

Fx = 22N

Explanation:

There are 2 possible scenarios for this problem:

1.- The 10N force is in the same direction of the acceleration. In this case the other force would be:

F1 - Fx = m*a     where F1 = 10N, m=6kg, a = 2m/s2

Fx = F1 - m*a = -2N    The negative result tells us that this is not possible.

2.- The 10N force is in the opposite direction of the acceleration. In this case the other force would be:

Fx - F1 = m*a     Fx = m*a + F1 = 22N

Yanka [14]

Answer:

C) 2.24 s

Explanation:

Speed of sound in air at 25 degree = 346 m /s

Speed of sound in sea water = 1533 m/s

Time taken by sound to reach dolphin

= 1000 / 1533 = 0.6523 s

Time taken by sound to reach boatman

1000/ 346

= 2.89 s

Difference

= 2.89 - .6523

= 2.24 s
