Sketch position-versus-time graphs (x versus t or y versus t) for the following motions. Include appropriate numerical scales along both axes. A small amount of computation may be necessary. 1. A parachutist opens her parachute at an altitude of 1500 m. She then descends slowly to earth at a steady speed of 5 m/s. Start your graph as her parachute opens. Trucker Bob starts the day 120 miles west of Denver. He drives east for 3 hours at a steady...

The above graph plots final velocity on the vertical axis and
\frac{1}{elapsed\:time}1 e l a p s e d t i m e on the horizontal
axis. It is easier to draw a Constant Acceleration Line (e.g., the
two upwardly sloping lines) on this graph than it would be to draw
a Constant Acceleration Line on a graph that used identical data,
but had "elapsed time" on the horizontal axis, because:
A. Using
1elapsedtime gives you a straight Constant Acceleration

Please help me
A San Francisco cable car is pulled by a cable running under the street. The cable moves at a constant speed of 9.50 mi/hr. The person who operates the cable car (called a gripman) operates a grip that grabs hold of the moving cable. (See Figure 2.) The gripman can allow the cable to slide through the grip so that the car can move at a speed that is slower than the cable. In Figure 2 the...

A cheetah starts at x = 0 and a gazelle starts at x = 0.5 km. The cheetah starts running straight towards the gazelle at steady speed 80 km/hr (he’s tired) and, at the same instant, the gazelle runs straight away from the cheetah at steady speed 60 km/hr. Draw a reasonable graph with the position x vertically and the time t horizontally, including vertical and horizontal tic marks (you can use km and hr as the units if you...

1. Cheetahs can accelerate to a speed of 20.0 m/s in 2.50 s and can continue to accelerate to reach a top speed of 27.6 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +?+x direction point in the direction the cheetah runs. Express the cheetah's top speed ?top in miles per hour (mi/h)(mi/h) . vtop = Starting from a crouched position, how much time ?accel does it take a cheetah...
