(4.2.95) At time t = 0, a car begins to accelerate at 3.0 m/s². After 4.0s of motion, the car stops accelerating and continues at constant velocity for an addition 4.0s. Then, the car brakes, decelerating at 6.0 m/s² until it comes to rest. (a) Calculate the position of the car at one second intervals, starting at t = 0, then t = 1s, 2s, and so forth, for the entire time the car is in motion. You do not need to show your calculations for this part. A table will suffice. (b) Calculate the velocity of the car at t= 0, t = 4.0s, t = 8.0s, and the stopping time. (c) On a single graph, plot the position, velocity, and acceleration of the car as a functions of time. The plot should include all data calculated in parts (a) and (b) of the problem. The rest you can sketch in.

The trap-jaw ant, found throughout tropical South America, catches its prey by very rapidly closing its mandibles around its victim. (Figure 1) shows the speed of one of its mandible jaws versus time in microseconds. What is the magnitude of the maximum acceleration of the ant's mandible? The mass of a trap-jaw ant's mandible has been estimated to be about 1.1×10−7kg1.1×10−7kg. Estimate the maximum force exerted by one mandible.

A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 68.6 m/s in 7.00 seconds. She then pulls the parachute cord and after a 2.7-second constant deceleration, descends at 10.5 m/s for 3.6 * 10' seconds, reaching the ground. From what height did the parachutist jump? answer in meters. (assume g = 9.8 m/s? )
A boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided. Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?

A car drives around a circular track of diameter 161 m at a constant speed of 47.4 m/s. During the time it takes the car to travel 256 degrees around, what is the magnitude of the car s average acceleration? Hint: Do not calculate instantenous accelleration. Instead calculte the average acceleration over the fraction of a complete lap. Average acceleration equals change in velocity divided by change in time, and that this is a two-dimensional situation so you'll have to calculate the x and y components of the average acceleration first and then figure out the magnitude. Remember also that ax = Δvx/Δt and ay = Δvy/Δt. 0 m/s^2 27.91 m/s^2 13.96 m/s^2 9.84 m/s^2
Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.41 m, and observe that it hits the floor 0.421 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 1 43.5 m/s^2 2 43.5 m/s^2 3 13.6 m/s^2 4 20.4 m/s^2
