A boy throws a rock horizontally with a velocity of 8.0 m/s from a bridge. It falls 19.0 m to the water below. What is the magnitude of the velocity of the rock just before it hits the water?
A boy throws a rock horizontally with a velocity of 8.0 m/s from a bridge. It falls 19.0 m to the water below. What is the magnitude of the velocity of the rock just before it hits the water?
If vx is the initial horizontal velocity, g is the acceleration due to gravity, the time taken for the rock to reach water is t, distance is d, then,
Vertical component of velocity vy is,
