Aball rolls down an incline 12 m long in 3.0 s.
a. assuming that the ball is uniformly accelerated, what is its average speed?
b. what is its final speed? 2. a ball rolls down a hill with a constant acceleration of 3.0 m/s^2.
a. if it starts from rest, what is its speed at the end of 4.0 s?
b. how far did it move? 3. a car starting from rest is accelerated at the constant rate of 3.0 m/s^2.
a. what is its speed at the end of 8.0 s ?
b. how far did it travel during the first 8.0 s?

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
