- A ball is kicked with an initial horizontal velocity of 16 m/s and initial vertical velocity of 10 m/s. What is the maximum height the ball goes above the ground? Use g = 10 m/s2.A ball is suspended from a light 1.3 m string . The string makes an angle of 24 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1m/s. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)? What will be the maximum angle, in degrees, the string will make with the vertical?Acceleration is sometimes expressed in multiples of g, where g = 9.8 m/s2 is the magnitude of acceleration due to the earth's gravity. In a test crash, a car's velocity goes from 26 m/s to 0 m/s in 0.15 s. How many g's would be experienced by a driver under the same conditions?
- On the moon, the gravitational acceleration is 1/6 x g of Earth. If you shoot a golf ball on the moon with a launch angle of 25 degrees and an initial velocity of 22 m/s, how high is its peak height? How many times higher did it go than it would have on Earth?A thoughtful person on a bridge reflecting on his awesome Physics class sees a small stone by his feet. Hmm, he thought to himself. Using his foot he slowly nudged the stone off the surface of the bridge and using his cell phone he timed how long it took to hit the water, about 1.75 s. How high (m) is the bridge above the water? (neglect air resistance)On the planet Koozebane, if a pebble is dropped from height h, it falls to the surface in time t. Data for the acceleration = 4.100 [m/s^2]; the height = 4.900 [m].

From the window of a building, a ball is tossed from a height yo above the ground with an initial velocity of 8.90 m/s and angle of 22.0° below the horizontal. It strikes the gyound 6.00 s (a) If the base of the building is taken to be the origin of the coordinates, with upward-the positive y-direction, what are the initial coordinates of the ball?

- A missile silo is used to launch military rockets vertically upward out of the silo, giving the rocket an initial speed of 79.6 m/s at ground level. As the rocket clears the silo, the engines fire, and the rocket accelerates upward at 3.90 m/s2 until it reaches an altitude of 1,080 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s². (You will need to consider the motion while the engine is operating and the free-fall motion separately. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Determine the velocity of the rocket (in m/s) at the end of the engine burn time and also the burn time (in s). (For the velocity, indicate the direction with the sign of your answer.) velocity at end of engine V = 92.22 Check your kinematic equation relating vo, V1, ay, and AYo → 1 (where velocity of rocket as it clears the silo, v, = velocity of the rocket at…The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 2.15 m above the floor. The ball hits the floor 0.265 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 61.2 m/s^2 30.6 m/s^2 45.9 m/s^2 97.9 m/s^2An astronaut exploring a distant solar system lands on a planet with a gravitational acceleration of 7.46 m/s2.
