The engine of a 1000 kg sports car rotates the tires, creating a et forward pushing force F on the tires of the car that varies as a function of distance. The force is shown below. If the car starts at rest, what is the speed of the car after traveling 500 meters? Force 1x104 N t 0 distance 0 m/s 71 m/s 100 m/s 141 m/s 200 m/s 500 m
Problem 4 A car travels along a straight road at a speed of 20 m/s, it decelerates uniformly to a stop over a period of 30 seconds; the car then it travels in the opposite of the original direction accelerating uniformly to a speed of 30 m/s in that direction over a period of 15 seconds a) Prepare a scaled time-velocity graph. b) Prepare a scaled time-acceleration graph. c) Prepare a scaled time-distance traveled graph. d) Determine average velocity of...
A low-flying cropduster A is moving with a constant speed of 40 m/s in the horizontal circle of radius 300 m. As it passes the twelve-o'clock position shown at time t = 0 car B starts from rest from the position shown and accelerates along the straight road at the constant rate of 3m / (s ^ 2) until it reaches a speed of 30m / s after which it maintains that constant speed. Determine the velocity and acceleration of...

B) Determine the normal force exerted by the car on the 80-kg driver. C) Determine the car speed at which the normal force on the driver equals zero.
One member of your group owns a sports car and has recorded some data for the straight-line motion of the car. The figure below shows part of the velocity data for the motion.(a) Determine the total distance (in m) the car traveled in the 50-s interval by evaluating the area under the red-brown graph line.(b) What distance (in m) does the car travel between the times t = 10 s and t = 40 s? (c) Draw a graph of its...
A 1100 kg car traveling at 20 m/s goes over a hill. At the top, the hill provides an upward normal force of 5600 N. (a) Assuming the hill has a circular profile, find the radius of curvature of the hill. (b) What is the maximum speed the car can go over the hill without ramping the car off the ground?
