If a hockey puck is made to slide along a straight line on a completely frictionless surface, which statement about the motion o
2 answers:
Answer:
The hockey puck will continue moving with constant velocity along a straight line.
Explanation:
As per Newton's first law we know that when there is no net force on an object then the velocity of object will always remains constant
Or we can say that the acceleration of an object will be zero when the force applied on the object is zero.
As per Newton's law we know
so we will have
a = 0
so object will continue in straight line with same uniform speed without any change in magnitude as well as any change in direction
so correct answer will be
The hockey puck will continue moving with constant velocity along a straight line.

Op here is another problem exactly like that. Just plug in your variables instead. And remember, time is never negative.
Answer:
(a) A = m/s^3, B = m/s.
(b) dx/dt = m/s.
Explanation:
(a)
Therefore, the dimension of A is m/s^3, and of B is m/s in order to satisfy the above equation.
(b)
This makes sense, because the position function has a unit of 'm'. The derivative of the position function is velocity, and its unit is m/s.
