Motion in One Dimension - SAT Subject Test in Physics
Card 0 of 4
Near the surface of the earth, a projectile is fired from a canon at an angle of 
degrees above the horizon and an initial velocity of 
meters per second. Which of the following expressions gives the time it takes the projectile to reach its maximum height?
Near the surface of the earth, a projectile is fired from a canon at an angle of
At the maximum height of projectile motion, 
and because this takes place near the surface of the earth we know 
which we can plug into the equation:
We can then rearrange for 
Next substitute this value into the equation 
to get the correct answer
At the maximum height of projectile motion,
We can then rearrange for
Next substitute this value into the equation
Compare your answer with the correct one above
