Chapter 1, Problem 47GP
Problems 39 through 45 are motion problems similar to those you will learn to solve in Chapter 2. For now, simply interpret the problem by drawing a motion diagram showing the object's position and its velocity vectors. Do not solve these problems or do any mathematics.
43. The giant eland, an African antelope, is an exceptional jumper, able to leap 1.5 m off the ground. To jump this high, with what speed must the eland leave the ground?

The particle flies from the origin of the coordinate system with an initial velocity of 3.0i ms-1 and moves with constant acceleration a = (-1.0i-0.5 j)m·s-2 what is a speed of the particle at the moment when its x-coordinate takes on the greatest value? what is position of the particle at that moment? Thank Youarrow_forwardIn kinematics it may be necessary to analyze a situation in which particles do not exhibit regular displacement throughout their movement, so that we cannot use just a mathematical equation to describe their velocity, acceleration and displacement. In cases like these, we use graphs to represent the motion of a particle, since the fundamental equations of speed and acceleration have geometric relationships with the graphs that represent them. Regarding the graphs of acceleration as a function of time, position as a function of time and speed as a function of time, it can be stated that: Choose one:a. The difference between velocities v2 and v1 is numerically equal to the area under the position curve between time t1 and t2, and therefore can be calculated by the derivative: v2-v1 = dS / dt. The difference between the accelerations a1 and a2 is numerically equal to the area under the velocity curve between the time t1 and t2 and can be calculated by the derivative: a2-a1 = dv / dt.B.…arrow_forwardIn kinematics it may be necessary to analyze a situation in which particles do not exhibit regular displacement throughout their movement, so that we cannot use just a mathematical equation to describe their velocity, acceleration and displacement.
