Answer:

Time, t = 19.20 seconds.

Explanation:

Given the following data;

Force = 452N

Velocity = 155m/s

Mass = 56kg

To find the time;

[tex] Force = \frac {mass * velocity}{time} [/tex]

Substituting into the equation, we have;

[tex] 452 = \frac {56 * 155}{time} [/tex]

Cross-multiplying, we have

[tex] 452t = 8680 [/tex]

[tex] Time, \; t = \frac {8680}{452}[/tex]

Time, t = 19.20 seconds.
