A soccer player kicks a rock with an initial velocity of 0.50 m/s from a height of 4.0 meters. What is the speed of the ball 0.70 second after it is released?

Question

Vi = 0.50 m;s
h = 4 m
t = 0.70 s

Answer 1

You know the intial horizontal velocity.
the final vertical velocity is..

vfv=gt find that, then add it to the horizontal velocity as a VECTOR.

vf=sqrt(vfv^2 + Vihorz^2)

Answer 2

A player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 m/s. What is the horizontal velocity component of the ball to the nearest tenth of a m/s?

Answer 3

A golfer tees off and hits a golf ball at a speed of 31 m/s and at an angle of 35 degrees. How long was the ball in the air? Round the answer to the nearest tenth of a second.
