hen he leaves the floor. It reaches a maximum height of 1.80 m above the floor and is at elevation 0.860 m when he touches down again. (a) Determine his time of flight (his "hang time"). (b) Determine his horizontal velocity at the instant of takeoff. m/s (c) Determine his vertical velocity at the instant of takeoff. m/s

A ball is thrown upward from the ground with velocity vi= 14 m/s and reaches height of h above the ground before falling back down. Take the upward direction to be positive. Refer to the figure. Neglect Air resistance. The acceleration in m/s to the ball when it is in the air is -9.8 m/s. The velocity of the ball in meters sped second, when it reaches the top of its trajectory is 0 m/s. Enter an expression for the maximum height, h, the ball reached in terms of vf, vi, and a. The value of h in meters is 10 m. Enter an expression for the time it takes for the ball to travel from the ground to the top, delta t, in terms of vi, vf, and a. The value of delta t in seconds is 10s. The total displacement in meters, of the ball going through its entire motion: reveling from the ground to the tio and then falling back to the ground is 0m. Enter an expression for the total time of flight of the ball: the time from when it is launched to when it lands back in the ground. Express this in terms of…

A ball is thrown vertically upwards from the ground at a speed of 15.0 m/s. At what time/s will it be at a height of 4.00 m (in seconds)     hint: there will be two answers. Type both in the box (in seconds)

The height above the ground of a drone is given by h = 3.50 t³, where h is in meters and t is in seconds. Calculate at t = 2.50 s (a) the height of the drone above the ground and (b) the velocity of the drone. At this time (t = 2.50 s) the drone releases a package (c) how long does it take the package to reach the ground? Include a complete diagram of the situation.
