a balloon is moving upwards with a speed of 5m/s when it is height 98m.a packet dropped from it.what is velocity of packet when it strikes the ground?

Answer»

When the packet FALLS from the BALLOON it has an initial velocity of 5 m/s.

The ACCELERATION is the acceleration due to GRAVITY which is 10m/s²

S = 98m

We will use the following equation of motion :

V² = U² + 2gs

V² = 25 + 2 × 10 × 98

V² = 1985

V = 44.55 m/s
