A truck falls from a bridge into the river in 0.5 s. let g = 10 ms–2,...
h = ut +(½)at2
Initial velocity , u = 0, t = 0.5s, a = 10 ms–2
h = 0 × 0.5 + (½)× 10 × (½) × (½)
= 1..25 m

A truck falls from a bridge into the river in 0.5 s. let g = 10 ms–2,...
To solve this problem, we can use the kinematic equation for free fall:

h = (1/2)gt^2

Where:
h = height of the bridge
g = acceleration due to gravity (10 m/s^2)
t = time of fall (0.5 s)

Substituting the given values into the equation, we have:

h = (1/2)(10)(0.5)^2
h = (1/2)(10)(0.25)
h = 1.25 meters

Therefore, the height of the bridge from the water surface is 1.25 meters.
