1. The velocity of an object traveling along the x-axis changes from 20 m/s to 60 m/s in 10 seconds. What was the displacement that occurred during this time? 2. An object moving along the x-axis initially has a velocity of 60 m/s and is slowing rest? down at the rate of 4 m/s per second. How far (in meters) will it travel before coming to 3. An accelerating object travels 12 meters from rest in a certain time. How...
A box accidentally drops from a truck traveling at a speed of 20.0 m/s and slides along the ground for a distance of 30.0m. Calculate: The acceleration of the box (assuming it is constant while sliding) The time to come to rest. The distance traveled during the first second after falling off the truck
4. An object travels 40.0 m east at a constant speed of 10.0 m/s. The object then travels 30.0° east of north, starting at 10.0 m/s but undergoing a constant acceleration to a final speed of 20.0 m/s over a period of 10.0 seconds. What is its total displacement?
An object with a mass of 9.00 g is moving to the right at 14.0 cm/s when it is overtaken by an object with a mass of 25.0 g moving in the same direction with a speed of 20.0 cm/s. If the collision is elastic, determine the speed of each object after the collision in centimeters per second. 25.0 g object cm/s 9.00 g object cm/s

A sinusoidal wave is traveling on a string with speed 28.0 cm/s. The displacement of the particles of the string at x = 8.3 cm is found to vary with time according to the equation y = (1.3 cm) sin[1.6 - (5.4 s-1)t]. The linear density of the string is 6.4 g/cm. What are (a) the frequency and (b) the wavelength of the wave? If the wave equation is of the form y(x,t) = ym sin(kx - ωt), what are...
