ANSWER:
Problem 75 GP
Step-by-step solution
Step 1 of 2
The dart will follow a parabolic path consistent with the projectile motion.
Time taken by dart to go up and down = 4 s.
Therefore, time taken for upward motion is half of the total flight time = 2 s.
Taking upward direction as positive, for the vertical displacement
The dart travels up with a speed of 19.6 m/s.
