A trebuchet fires a tennis ball with an initial velocity of 78.4 m/s at an angle of 52 degrees with the horizontal. (Neglect friction and assume the ball lands at the same height from which it was launched).
1 ) calculate the total flight time of the tennis ball
2 ) calculate the maximum altitude the ball attains during its flight
3 ) calculate the horizontal distance the tennis ball travels before impacting the ground
4 ) calculate the final velocity of the tennis ball just before impacting the ground
2 )
Sketch a scale drawing of the above question. The diagram should include the parabolic path with the following labeled quantities : Make sure to use a ruler and protractor for a scaled sketch
the firing angle, horizontal velocity, vertical velocity, actual velocity, maximum height, projectile horizontal range
Use the following scales : 1 cm = 10 m/s for velocity
1 cm = 30 m for distance
