Shown below is a graph of velocity versus time for a moving object. The object starts at position x = 0 m at t = 0 s. What is the final position in meters, from t = 0 s to t = 2.0 s?

At an air show, a jet plane has velocity components vx =695km/h and vy  =415km/h  at time 4.35 s and vx =938km/h and vy =365km/h at time 7.52 s.   Please answer A,B,C,D Thank you.

For this problem, assume the values on the axes of the graph have 1 decimal place of precision when measured.An athlete is training on a 100 m long linear track. His motion is described by the graph of his position vs. time, below.

Please answer all the parts

If an average-size man jumps from an airplane with an open parachute, his downward velocity t seconds into the fall is v(t) = 20(10.2) feet per second. (a) Use functional notation to express the velocity 3 seconds into the fall. Calculate it. ft per sec (b) Explain how the velocity increases with time. Include in your explanation the average rate of change from the beginning of the fall to the end of the first second and the average rate of " change from the fourth second to the fifth second of the fall. This answer has not been graded yet. (c)-Find the terminal velocity. ft per sec (d) Compare the time it takes to reach 99% of terminal velocity here with the 25 seconds it took a skydiver with his parachute closed to reach 99% of terminal velocity in Example 2.1. On the basis of the information we have, which would you expect to reach 99% of terminal velocity first, O feather feather or a cannonball? O cannonball Need Help? Read It

The functional relation between the displacement x in meters and the time t in seconds is given by x = At 2 + Bt + C where A, B, and C are constants. Find the functional relationship between the (a) velocity and the time, and (b) acceleration and the time. What are the values of the velocity and the acceleration at the instant t= 4seconds?

A car starts from 2.00 m/s and accelerates at 4.00 m/s2 for 6.0 s, it coasts for 5.00 s, and then slows down at a rate of 2.00 m/s2to a stop. How far has it traveled, in meters? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

What is the unit for acceleration? A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car. A blue beetle starts from rest and in 4.5 seconds is flying 2.2 m/s. What is the acceleration of this insect?

A hot air balloon is moving vertically upwards at a constant rate of 9.0 m/s. As the balloon rises, a package is dropped from the balloon and it takes 5 s to hit the ground. How far did the package fall?   Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Please use grade 12 kinematics and label the variables as v1, v2, a (Acceleration), t (time), d (displacement) Thanks!

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=?
