• Question #ee704
  
• A projectile is shot at an angle of `pi/8` and a velocity of `27 m/s`. How far away will the projectile land?
  
• Explain the forces acting, including friction, when an object is stationary or moving on an inclined plane. What coordinate system do we use?
  
• Question #cdb75
  
• How do you test for convergence of `Sigma (3n-7)/(10n+9)` from `n=[0,oo)`?
  
• A projectile is shot from the ground at an angle of `pi/6` and a speed of `5 m/s`. When the projectile is at its maximum height, what will its distance, factoring in height and horizontal distance, from the starting point be?
  
• A ball with a mass of `360 g` is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of `24 (kg)/s^2` and was compressed by `5/3 m` when the ball was released. How high will the ball go?
