The position of a particle moving along the x -axis varies with time according to x(t)=5.0t24.0t3 . Find (a) the velocity and acceleration of the particle as functions of time, (b) the velocity and acceleration at t=2.0s , (c) the time at which the position is a maximum, (d) the time at which the velocity Is zero, and (e) the maximum position.
A projectile is launched from the point (x = 0, y = 0), with velocity (12.0i19.0j)m/s2, at t = 0. (a) Make a table listing the projectiles distance r from the origin at the end of each second thereafter, for 0 t 10 s. Tabulating the x and y coordinates and the components of velocity vx and vy will also be useful. (b) Notice that the projectiles distance from its starting point increases with time, goes through a maximum, and starts to decrease. Prove that the distance is a maximum when the position vector is perpendicular to the velocity. Suggestion: Argue that if v is not perpendicular to r, then r must lie increasing or decreasing. (c) Determine the magnitude of the maximum displacement. (d) Explain your method for solving part (c).
Galileo thought about whether acceleration should be defined as the rate of change of velocity over time or as the rate of change in velocity over distance. He chose the former, so lets use the name vroomosity for the rate of change of velocity over distance. For motion of a particle on a straight line with constant acceleration, the equation v = vi + at gives its velocity v as a function of time. Similarly, for a particles linear motion with constant vroomosity k, the equation v = vi + kx gives the velocity as a function of the position x if the particles speed is vi at x = 0. (a) Find the law describing the total force acting on this object of mass m. Describe an example of such a motion or explain why it is unrealistic for (b) the possibility of k positive and (c) the possibility of k negative.
One of the fastest recorded pitches in major league baseball, thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h (Fig. P3.8). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate, 60.5 ft away? Figure P3.8 Tim Lincecum throws a baseball.
(a) If a person can jump a maximum horizontal distance (by using a 45 projection angle) of 3.0 m on Earth, what would be his maximum range on the Moon, where the free-fall acceleration is g/6 and g = 9.80 m/s2? (b) Repeat for Mars, where the acceleration due to gravity is 0.38g.
Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 3.45 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 36.4 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 7.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance. With what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground? Where is Henrietta when she catches the bagels?
Two ducks, Donald and Cassiopeia, are gliding gracefully toward eachother along a pond, in a straight line. Donald is initially moving at v =0.500 m/s, and begins accelerating at 0.100 m/s2 at t = 0 s. Cassiopeiamoves at a constant speed of v = 0.700 m/s. If they are initially separatedby 25.0 m, where will they collide? Take Donald’s initial position as theorigin. How long will it take for them to collide?
Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 3.30 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 52.5 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 9.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance. I.

The velocity function of a particle moving along a horizontal line is given by v(t) = t2-8t+15, where t >= 0 is in seconds. The particle is 5/3 units to the left of the origin at the second instant when it changes direction. 1. Determine th etime interval (s) on which the particle is both moving to the right and slowing down. 2. Find the position function of the particle.
III. The velocity-time graph of a particle in one dimension is shown in the figure. Assuming that the particle started at x0 = 0 m, what are the instantaneous position x(t) and velocity v(t) equations (in the form compliant with SI units) that correspond to the interval - from A to B? - from B to D? - from D to E? Roughly sketch the corresponding a-t and p-t ploots for the given v-t plot.

A rocket is fired at a speed of 83.0m/s from ground level, at an angle of 66.0degrees above the horizontal. The rocket is fired towards an 28.8m high wall, which is located 25.0m away. The rocket attains its launch speed in a neglibly short period of time, after which its engines shut down and the rocket coasts. By how much time does the rocket clear the top of the wall?
