A projectile exits a launch tube with a velocity of 255 m/s. While accelerating through the launch tube, the projectile moves a distance of 1.850 m. Determine the acceleration of the projectile (assume a uniform acceleration). Which equation should you use to solve for acceleration? Choice 1 V = v, + aat Choice 2 Ax = vAt +(1/2)aAt? Choice 3 v = v,? + 2aAx Choice 4 Ax = 1/2(v, + v)At

1. A baseball is thrown upward with an initial velocity magnitude of 35.0 m/s. What is its velocity at t = 2.00 s?

The vertical displacement (in m) of a plane is  1.5 t2 up; t is the time (in s) after takeoff. The plane releases a package 2.0 s after takeoff. What is the magnitude of the velocity (in m/s) just as the package hits the ground? Report your answer in the appropriate number of significant digits. Answer value

1. One object is dropped from a height h = 1.0202030304040505 m (initial velocity is zero) and it hits the ground after a time t₁. A second object is launched horizontally from the same height h = 1.0202030304040505 m (as shown in the figure below) with the horizontal velocity vo = 1.0102030405 m/s, and it hits the ground after a time t2. Compute the time difference At = t₂ - t₁. (Neglect the air friction). EXPLAIN YOUR ANSWER or SHOW YOUR WORK. A numerical value is required for credit.

A projectile is shot perfectly horizontally with a speed of 7.02 m/s, and a height of 6.14 m. How far off the ground will it be after 0.459 s? Express your answer in meters to 3 significant figures. Use g=9.81 m/s².

A mountain lion jumps to a height of 2.80 m when leaving the ground at an angle of 43.1°. What is its initial speed (in m/s) as it leaves the ground?  m/s

A dog jumps in a horizontal direction with an initial speed of vo=3.2 m/s from the edge of a table and lands L=2.3 m away from the table. a.hold long does it take the dog to hit the ground? (3 sig fig) b.what is the height in meters of the table? (3 sig fig)

The height (in meters) of a projectile shot vertically upward from a point 4 m above ground level with an initial velocity of 25.5 m/s is h = 4 + 25.5t − 4.9t2 after t seconds. When does it hit the ground and at what velocity does it hit the ground

Problem 4: A particle moving along a straight path has an acceleration defined by a = 0.6s + 3.6 ft/s², where s is in feet. If the particle's speed is 1.2 ft/s at s = 0, find its speed when s = 8 feet.

Time left 0:39:02 The Burj Khalifa is the tallest building in the world with a height of 0.828 km. On his delivery on Christmas Eve, Santa Claus accidentally bumps into the Burj Khalifa and drops a toy from the very top of the building. What is the magnitude of the velocity (in m/s) of the toy 0.018 km from above the ground? Neglect air resistance. 9 9.81m/8² Do NOT include units in your answer. Round your answer to 2 decimal places. Do NOT change to scientific notation. Ignore significant figures. Answer
