How long does the ball take to reach that point?A mountain lion jumps to a height of 2.65 m when leaving the ground at an angle of 42.9°. What is its initial speed (in m/s) as it leaves the ground?A juggler throws a bowling pin straight up with an initial speed of 6 m/s from an initial height of 3.4 m. How much time elapses until the bowling pin returns to the same initial height?
- Mature salmon swim upstream, returning to spawn at their birthplace. During the arduous trip they leap vertically upward over waterfalls as high as 3.31 m. With what minimum speed (in m/s) must a salmon launch itself into the air to clear a 3.31-m waterfall? in m/sA stone is thrown from the top of a building with an initial velocity of 20.0 m/s straight upward, at an initial height of 50.0 m above the ground. The stone just misses the edge of the roof on the its way down. Determine (d) the time needed for the stone to reach the ground. Ans: t = 5.83 s (e) the velocity and position of the stone at t = 5.00s Ans: v = -29 m/s & y = -22.5 mA projectile is launched in the horizontal direction. It travels 2.050m horizontally while it falls 0.450m vertically, and it then strikes the floor. How long is the projectile in the air? What was the original velocity of the projectile?
- A puma (aka cougar or mountain lion) is one of the best jumpers among all animals. It can jump to a height of 12.0 feet high when it leaves the ground at an initial angle of 45°. What is the initial speed (in m/s) of the puma as it leaves the ground?An object is thrown vertically upwards by a person’s hands. While it is in contact with their hand, the object has an acceleration of ?=(2.00t^2+12.0t) m/s^2, with an initial velocity of zero. It is in contact with the person’s hands for 1.2 s. How high above the point of release does this object go? Ignore the air resistance and height change due to the motion of the hand.An object is thrown straight upward with an initial velocity of 11.7 m/s. What is the object's maximum upward displacement?
