A stone is thrown vertically up from a bridge with velocity 3m/s. If it strikes with water under the bridge after 2sec, the bridge is at a height of (g=10m/s)

A pebble is thrown vertically upwards from a bridge with an initial velocity of 4.9 m/s. It strikes the water after 2s. If acc. Due to gravity of 9.8 m//s^(2) (a) what is the height of the bridge ? (b) with what velocity does the pebble strike the water ?

A pebble is thrown vertically upwards from a bridge with an initial velocity of 4.9 m/s. It strikes the water after 2s. If acceleration due to gravity is 9.8 m//s^(2)(a) what is the height of the bridge? (b) with what velocity does that pebble strike the water?
