Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 3.74 seconds later. (A) If the speed of sound in air is 343 m/s at the rock climbers location, what is the depth of the chasm? (B) What is the percentage of error that would result from assuming the speed of sound is infinite?
2. A mouse enters a basement room through a hole in one of the walls. It then travels through the room before running out through a hole in another wall. The mouse is filmed by a surveillance camera on the ceiling. A physics student analyzes the recording and sets up the equations for movement to the mouse. The student uses x and y axes along the two walls with holes in them. The x and y positions as a function of time are
x (t) = −0.10 m / s2 · t2 + 1.8 m / s · t
y (t) = −0.20 m / s2 · t2 + 2.0 m / s · t + 3.0 m
(a) Draw the motion of the mouse in the xy plane. For example, you can plot the position every second.
(b) Determine the speed and acceleration of the mouse after 3.0 s. Draw the vectors in the figure in (a).
(c) When does the mouse run out through the second hole?
I'm solving 7.52 b) and I got Waa = 0 ( it is right answer ) but my Wab component comes out 0 too , but it is wrong . So I wonder where I made the mistake ? Wab should be ihqB0/2m

- Bob has just finished climbing a sheer cliff above a beach, and wants to figure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the beach below with a long measuring tape. Bob is a pitcher and he knows that the fastest he can throw the ball is about vo = 34.5 m/s. Bob starts the stopwatch as he throws the ball (with no way to measure the ball's initial trajectory), and watches carefully. The ball rises and then falls, and after t₁ = 0.510 s the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball landed x = 128 m from the base of the cliff. How high up is Bob, if the ball started exactly 2 m above the edge of the cliff? 2 m -- X Bob's position= x10 TOOLS marrow_forwardCan you help me, i need a shortcut on how to know when should i use cosine or sine.here's the problem and the solution One morning, Connie walks from her house to go to a store that is 500 ft, S 40o W from her house.

It is afreezing cold day in the artic, which means that sound travels through air at only 295.0 m/s.
