A bullet is fired from ground level with a speed of 150 m/s atan angle of 30 deg

Question

A bullet is fired from ground level with a speed of 150 m/s atan angle of 30 degrees above the horizontal. What is the velocityof the bullet when it is at the highest point of itstrajectory? A. 120 m/s B. 0 m/s C. 130 m/s D. 75.0 m/s A bullet is fired from ground level with a speed of 150 m/s atan angle of 30 degrees above the horizontal. What is the velocityof the bullet when it is at the highest point of itstrajectory? A. 120 m/s B. 0 m/s C. 130 m/s D. 75.0 m/s A. 120 m/s B. 0 m/s C. 130 m/s D. 75.0 m/s

Explanation / Answer

initial speed=150 m/s initial horizontal velocity=150*cos30 since horizontal acceleration =0 velocity at the highestpoint=150*cos30 vertical velocity at the highest point=0 velocity of the bullet at the highest point=horizontalvelocity=150*cos30=129.9 m/s or 130 m/s so the answer is C.130 m/s
