An arrow is shot horizontally from a height of 4.9 m above the ground. The inital speed of the arrow is 45 m/s. Neglecting fritction, how long will it take the arrow to hit the ground?


Expert Answer

Step 1

To determine: The time taken by the arrow to reach the ground.

Given information: The height from which the arrow is thrown is 4.9 m and the horizontal speed of the arrow is 45 m/s and the initial vertical speed is zero. Resistance of motion due to friction is neglected.

The arrow experiences constant vertical acceleration and constant horizontal speed.

Step 2

Write the kinematic expression for distance travelled

Here, s is the vertical distance travelled by the arrow, u is the i...
