Question

In our demonstration with the crate on ice, the crate after being pushed and let go (set force equal to zero) slides on the ice without friction.
Which graph correctly represents the puck's velocity as a function of time?
B
v (m/s)
Av (m/s)
A.
1 (s)
t (s)
v (m/s)
C
r(s)
C₂
v (m/s)
r(s)
D.

Expert Solution

Step 1

Since friction is zero and and there is no force on the crate then by Newton's first law (In absence no force the object maintain it's positive (motion or rest)) the crate will move always with constant velocity.

Hence first graph (A) is correctly represent this phenomenon.
