An object was observed to have velocity v1 in m/s at time t1 seconds and later velocity v2 in m/s at time t2 seconds: v1=0; t1=0.6; v2=14; t2=4.0 Units are m/s and s. Find the average acceleration of the object in m/s/s.

For the following function models the position s(t)s(t) of an object moving along a stright line, where tt is in seconds and ss is in meters. s(t)=t2-6t Find the simplified expression for the average velocity from t=7t=7 to t=7+ht=7+h. s(t+h)-s(t)/h=?

Given v(t) = 21 + 20 t, where v is in m/s and t is in s, use calculus to determine the total displacement from t₁ = 1.5 s to t₂ = 3.1 s. Express your answer using two significant figures.

A car begins at the position x1 = 6.0.m with an initial velocity of 20.4 m/s. If the acceleration of the car is 7.80 m/s^2 find the velocity of the car when it has reached the point x2 = 25.0m in m/s. Just input the number in the answer box, don't input units.

The graph below shows the motion of an object. The average speed for the whole journey is 12 m/s. Find the time of acceleration, t, of the object. velocity / m s-1 A 20 ㅇ 20 time / s t O 10 s O 14 s O 12 s O 16 s

The x component of the velocity of an object moving along the x axis is given as vy = 4t – 3t where vy is in meters per sec and t in seconds. The x component of its average velocity over the interval of time from t =0 to t= 2 sec is: O -2m/s O 2 m/s O -4m/s

An object's position in the X-direction as a function of time is given by the expressio%3B x(t) = 5t2 + 2t where are quantities have proper SI Units. What is the object's average velocity in the x-direction between the times t = 1.71 s and t = 2.37 s. Just enter the number rounded to 3 significant figures and assume it has proper SI Units.

The acceleration of a particle is a constant. At t = 0 the velocity of the particle is (15.8î + 18.4ĵ) m/s.At  = 3.6 s the velocity is 10.5ĵ m/s. (Use the following as necessary: t. Do not include units in your answers.)   (b) How do the position (in m) and velocity (in m/s) vary with time? Assume the particle is initially at the origin.

A remotely controlled toy car travels along a straight line and its position changes with time following the law: x(t)=51³-1²+1 where time t is measured in seconds and the coefficients have such dimensions that the position x(t) is measured in meters. 10. What is the displacement of the car for the first 2 seconds since the start at t=0 s? 11. What is the average velocity of the car for the time period between the t=0s and t=2 s? 12. What is the instantaneous velocity of the cat at t=2s ? 13. What is the instantaneous acceleration of the car at t=2 s?

The acceleration of an object as a function of time is given by a(t) = 6.0 t² where t and a are in Sl units. If the object has a velocity 2.0 m/s at time t=0.0 s. What is the velocity of this object as a function of time?
