A hockey puck is sliding along on frictionless ice with a velocity of 4.42 m/s. Assuming it does not collide with anything, how fast will it be moving in 1.20 seconds?
no friction means no force
no force means no acceleration
no acceleration means constant velocity.
To find the speed of the hockey puck after 1.20 seconds, we need to understand that the object is moving with a constant velocity. Therefore, the speed remains the same throughout the motion.
Given that the hockey puck's initial velocity is 4.42 m/s, we can conclude that the speed will remain at 4.42 m/s after 1.20 seconds.
To determine the speed of the hockey puck after 1.20 seconds, we can use the concept of constant velocity. Since there are no external forces acting on the puck, its velocity will remain constant throughout its motion.
The given initial velocity of the hockey puck is 4.42 m/s. This represents the magnitude of its velocity.
To find the final velocity after 1.20 seconds, we can utilize the equation:
Final velocity = Initial velocity
So, the hockey puck will still be moving with a velocity of 4.42 m/s after 1.20 seconds.
