Homework # 20 - Projectile at an Angle Handout Problems (SHOW ALL YOUR WORK BELOW AND/OR ON A SEPARATE SHEET): Handout Problems: 1. A projectile, fired at an angle of 450 to the ground, takes 3 s to reach the top of its path. (a) How long does it travel before it hits the ground? (b) What acceleration does the projectile have? (c) What effect will increasing the angle at which the projectile is fired have on the horizontal component of the velocity of the projectile? (d) What effect will increasing the angle at which the projectile is fired have on its acceleration? 2. A projectile is shot upward at a 60 angle with the ground and a speed of 200 m/s. (a) Obtain the vertical and horizontal components of its velocity. (b) How far has the projectile gone horizontally at the end of the first 4.00 s? 3. A soccer ball is kicked up at angle of 50 with the horizontal at a speed of 30 m/s. (a) Find the highest point reached by the ball. (b) How long does it take to get to the highest point? (c) How long does the ball remain in the air? (d) How far away does the ball land
