A. Alhouse is thrown straight upward off a high building. The building is located somewhere on the surface of Earth. 4 seconds later, the mouse hits the ground. ASSUME: • The building is an unknown height. • The mouse takes 4 seconds to reach the ground. • The mouse's initial speed is 5 m/s DETERMINE: • The height of the building. 6 pts) B. Near the surface of Earth, a helicopter travels upward at a constant velocity. At some moment,...

1. An automobile starts from rest and accelerates to a final velocity in two stages along a straight road. Each stage occupies the same amount of time. In stage 1, the magnitude of the car's acceleration is 2.99 m/s2. The magnitude of the car's velocity at the end of stage 2 is 2.20 times greater than it is at the end of stage 1. Calculate the magnitude of the acceleration in stage 2. 2. The Space Shuttle travels at a...

At moment of time t=0 a projectile is fired directly upward with an initial velocity 192 ft/sec, and initial height 200 ft. Find: a)velocity and acceleration after t seconds, (b) velocity when projectile hits the ground, (c) time of travel from the highest point to the ground. Equation of motion is h"= -32, where h(t) is the height of projectile at moment t.

A hot-air balloonist, rising vertically with a constant velocity of magnitude v = 5.00 m/s, releases a sandbag at an instant when the balloon is y 42.0 m above the ground. After it is released, the sandbag is in free fall. y mto ground (a) Compute the position and velocity of the sandbag 0.250s after its release m m/s Compute the position and velocity 1.00 s after its release m m/s (b) How many seconds after its release will the...

Draw position, velocity, acceleration graphs for Lin Lee and Rodrigo and also label an image of this scenario with velocity and acceleration vectors. The Skydiving Club has asked you to plan a stunt for an air show. In this stunt, two skydivers will step out of opposite sides of a basket held up by a stationary hot air balloon 5,000 feet above the ground. The second skydiver will leave the basket 20 seconds after the first skydiver, but you want...

A whale swims at a constant velocity of 15 m/s southeast for 10 seconds, slows to a stop at a rate of 3 m/s^2, and then accelerates northwest at a rate of 2 m/s^2 for 5 seconds. (a) sketch the velocity versus time t for the entire motion. Assume the motion started at time t=0 seconds; (b) how long did the motion described last?; (c) find an expression of the whale's velocity as a function of time for the entire...

3. The following graph is a velocity-position plot that shows the velocity v versus height y of a ball that is tossed directly upward in the vertical direction. (Note: this is a different type of graph compared to the position-time and velocity-time graphs that you have seen in class.) a. What part of the ball's motion does this graph describe? (In other words, does it describe the ball's total overall motion up and down? Only the upward motion? Only the...

You throw a ball vertically upward with a velocity of 10 m/s from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s^2 downward, determine (a) the velocity v and elevation y of the ball above the ground at any time t, (b) the highest elevation reached by the ball and the corresponding value of t, (c) the time when the ball hits the ground and the corresponding...
