Answer:
4m/s
Explanation:
May be different considering how long the pole is and how heavy the firefighter is.
The magnitude<span> of a </span>velocity<span> vector is </span>called<span> speed. Supposethat a wind is blowing in from the direction at a speed of 50 km/h. (This meansthat the direction from which the wind blows is west of the northerly direction.) Apilot is steering a plane in the direction at an airspeed (speed in still air) of250 km/h

Rotational motion may be described analytically for bodies undergoing pure rotation.
Answer:
3) 52500N
Explanation:
We use the mathematical definition of impulse as follows;

were F is the force experienced, t is the time of impact, m is the mass of the object and v is the velocity of impact.
Given; m = 4.5kg, v = 35m/s, t = 3 milliseconds
however, 
From equation (1);
.
Substituting all necessary values into equation (2), we obtain the following;
