In a tug of war , two teams pull on the rope with a certain force. If team A pulls on it with a force of 225 N and team B pulls

kherson [118]

Answer:

135 N

Explanation:

Given that:

In a tug of war, team A pulls the rope with a force of 225 N; &

Team B also pulls with a force of 360 N

The magnitude of the resultant force is the difference between the two forces since they are positioned in the opposite direction.

Thus;

The magnitude = 360 N - 225 N

So, magnitude of resultant force on the rope = 135 N

A car is moving at a constant speed of 14 m/s when the driver presses down on the gas pedal and accelerates for 14 s with an acc

Vinil7 [7]

acceleration of car is 1.8 m/s^2

time = 14 s

initial speed = 14 m/s

so the final speed is calculated by

$v_f = v_i + at$

$v_f = 14 + 14 * 1.8$

$v_f = 39.2 m/s$

so the total distance moved in this interval of time is

$d = \frac{v_f + v_i}{2}* t$

$d = \frac{39.2 + 14}{2}* 14$

$d = 372.4 m$

now the average speed is given as

$v = \frac{d}{t}$

$v = \frac{372.4}{14}$

$v = 26.6 m/s$

so the average speed will be 26.6 m/s
