Bond [772]

Answer:

272.89g

Explanation:

Find the diagram to the question in the attachment below;.

Using the principle of moment to solve the question which states that the sum of clockwise moment is equal to the sum of anticlockwise moment.

Moment = Force * Perpendicular distance

Taking the moment of force about the pivot.

Anticlockwise moment:

The 85g mass will move in the anticlockwise

Moment of 85g mass = 85×36.6

= 3111gcm

Clockwise moment.

The mass of the metre stick M situated at the centre (50cm from each end) will move in the clockwise direction towards the pivot.

CW moment = 11.4×M = 11.4M

Equating CW moment to the ACW moment we will have;

11.4M = 3111

M = 3111/11.4

M = 272.89g

The mass of the metre stick is 272.89g

Speed1=20 m/s. time1=5sec

lina2011 [118]

Answer:

Explanation:

<h2>AVERAGE SPEED=</h2>

 $= \frac{s1 t1+ s2t2 + s3t3}{t1 + t2 + t3}$ 

 $= \frac{20 \times 10 + 30 \times 5 + 15 \times 5}{10 + 5 + 5}$ 

 $= \frac{200 + 150 + 75}{20}$ 

 $= \frac{425}{20}$ 

 $= 21.25 ms$
