A car of mass, 1200 kg is pulled with constant force of 3000N in 20s. Work out A) The acceleration resulted:

B) Distance travelled by the car, in the given time?

C) Work done by the engine of the car

D) The kinetic energy of the Car​

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
