## Question:

A cat chase a mouse across a 1.0 m high table. The mouse steps out of the way, and the car slides off the table and strikes the floor 2.2m from the edge of the table. When the car slid off the table what was it’s speed?

Answer is 4.9 m/s how do we get 4.9 m/s?

## Answer:

The car slid off the table at a speed of **4.90 m/s**.

**Given data:**

The **height **of table is, .

**Horizontal distance** slide by the car is, .

Apply the** second kinematic equation** of motion as,

Here, **u **is the** initial speed** of car, **g **is the **gravitational acceleration** and **t** is the **time**.

Now, the **speed of car** is calculated as,

Thus, the **car **slid off the table at a speed of **4.90 m/s**.
