At moment of time t=0 a projectile is fired directly upward with an initial velocity 192 ft/sec, and initial height 200 ft. Find: a)velocity and acceleration after t seconds, (b) velocity when projectile hits the ground, (c) time of travel from the highest point to the ground. Equation of motion is h"= -32, where h(t) is the height of projectile at moment t.
1. Suppose that a car weighing 2000 pounds is supported by four shock absorbers Each shock absorber has a spring constant of 6250 lbs/foot, so the effective spring constant for the system of 4 shock absorbers is 25000 lbs/foot. 1. Assume no damping and determine the period of oscillation of the vertical motion of the car. Hint: g 32 f/sec2 T314 2. After 10 seconds the car body is 1 foot above its equilibrium position and at the high point...
When a ball is thrown straight down from the top of a tall building, with initial velocity 30 ft/sec, the distance from the release point at time t in seconds is given by s(t)=16t^2+30t. If the release point is 300 ft above ground, what is the velocity of the ball at the time it hits the ground? I think you would have to average the feet per seconds but I'm not sure.
Uniform linear motion 5. (10 pts) A car moves with a constant velocity along a straight road. Its position is xi 0 m atti-0 and is x2 30 m at t2 3s a. what is the car's velocity at t = 1 s? b. What is the car's displacement between t 1.5 s and t2.5 s? 6. (15 pts) In an 8-km race, one runner runs at a steady 12 km/h and another runs at 14.5 km/hr. If they start...
need help with ANALYZE PART A AND B and FINALIZE EXPLORE A car is moving with constant acceleration along a straight road (A) Determine how the velocity and the displacement of the car vary with time if the car is initialy moving to the right with a speed of 9.0 m/s and has an acceleration to the right of 1.7 m/s (B) Determine the velocity as a function of time when the velocity is instead initially to the right and...

4. Two toy remote-controlled cars start from the same position, O, at time t-0. One car, C ,travels north at 4 m/s, while the other, C2, travels west at 2 m/s. (a) After two seconds, compute the rate of change of the distance between Ci and Cz. Draw a diagram to help you answer this question and the next and clearly state the units. Simplify your answer as much as possible. (7 pts.) (b) After two seconds find the rate...
