Rectilinear Motion

Question

A food packet is dropped from a helicopter rising up with a velocity of 4m/s. The velocity of the packet after 3sec will be……..

Easy

A

25.4 m/s
B

20.4 m/s
C

28.4 m/s
D

30.4 m/s

Solution

The food packet is initially moving upwards with the velocity of helicopter.
$\begin{array}{l} ∴ v = u - g t \\ = 4 - 9.8 \times 3 \\ = 4 - 29.4 \\ = - 25.4 m / s \end{array}$
(negative sign shows that it is moving down)
