Answer:
v = 3.08 m/s.
Explanation:
Given,
- Initial velocity of the block = u = 43 cm/s = 0.43 m/s
- mass of the block = m = 1.40 kg
- spring constant = k = 15.5 N/m.
- x = 0.650 m
At x = 0.650 m
Let 'a' be the acceleration of the block at x.
Total force due to the spring force on the blcok at x= kx
Hence the acceleration of the block at x is 7.19\ m/s^2.
Let 'v' be the velocity of the block at x.
From the kinematics,
Hence at the compression x = 0.650 m the velocity of the block is 3.08 m/s.
Answer:
An image can be seen in the mirror because the light reflected from an object falls on the mirror and it is reflected.
Answer:A force can be described as a push or a pull. Pushes and pulls can be seen to act on objects when they begin to move, speed up, slow down or change direction.
The image gallery on this page shows children at play using push and pull actions to move objects. Children use push and pull all the time while at play. While playing, students learn to manipulate objects and materials and make observations about their actions.
Teachers may use this teaching resource over a number of lessons to explore and develop their students' understanding that a push or a pull affects how an object moves or changes shape.
Explanation:
The Newton's second law of motion can be used to determine the why certain players are used certain positions because each player has unique mass and as such exert a unique force.
<h3>
What is Newton's second law?</h3>
Newton's second law of motion states that the force applied to an object is directly proportional to the mass and acceleration of the object.
F = ma
where;
- m is mass of the object
- a is acceleration of the object
Based on Newton's second law of motion, the force exerted by an object increases with increase in the mass of an object.
For example, most defenders in sports usually have large mass which increases the force exert on the opposing team.
Thus, the Newton's second law of motion can be used to determine the why certain players are used certain positions because each player has unique mass and as such exert a unique force.
