Question

toy truck moves off the edge of a table that is 1.25m high and lands 0.40m from the base of the table. (a)how much time passes between the moment the car left the table and the moment it hit the floor?

Answer 1

Answer:

it can be considered as horizontal projectile.

so the time will be

$\sqrt{2h \div g}$

which will give you 0.5 seconds.

Answer 2

Answer:

0.5 seconds passes.

Explanation:

The given situation can be considered as the projectile motion performed at a height "H". And for this kind of motion time taken to hit the floor  is given as,

$T=\sqrt{\frac{2H}{g} }$         (1)

Where,

T=time taken to hit the floor

H=height from where the projectile motion is performed

g=acceleration due to gravity=10m/s²

From the question we have,

H=1.25m

Distance from the table=0.40m

By substituting the required values in equation (1) we get;

$T=\sqrt{\frac{2\times 1.25}{10} }$

$T=\sqrt{0.25}$

$T=0.5 Sec$

Hence, 0.5 seconds passes.
