Newton's 2nd law of motion: Force = (mass) x (acceleration)
<em>Force on the ball = (mass of the ball) x (9.5 m/s²) to the right</em>
A can opener makes work easier by increasing force.
Explanation
Technically a can opener is a simple lever that increases the force with which we remove the cap of the can. Levers are rod shaped objects with fulcrum at one end and the length of the lever has a positive impact on the force.
considering the equation
work=force*distance
indicates that increasing the length of the lever/can opener increases the work done by it.
Answer:
5.53 m
Explanation:
= initial speed of shuffleboard disk =
= final speed of shuffleboard disk =
= Coefficient of kinetic friction between the disk and concrete court = 0.31
acceleration due to friction is given as
= distance traveled by disk before it stops
using the kinematics equation that fits the above the data, we have
Answer:
both magnitude and direction
Explanation:
When an object moves in a circular path, its motion is called uniform circular motion. In this motion, the force acting on it is centripetal force and it is moving under centripetal acceleration. This type of force acts towards the centre of the circle.
In this type of motion, the speed remains constant while the velocity keeps on changing. The object's centripetal acceleration remains constant in magnitude as well as direction.
Hence, the correct option is (3).
