The position of a particle moving along the x-axis is given by x = (13 + 11t − 1.5t2), where t is in seconds and x is in meters. What is the average velocity during the time interval from t = 1s to t = 4 s?

The position of an object as a function of time is given as x = At3 + Bt2 + Ct + D. The constants are A = 2.3m/s3, B = 1.8m/s2, C = −4.3m/s, and D = 2 m.(a) What is the velocity of the object at t = 12s? (b) What is the acceleration of the object at t = 0...

The velocity as a function of time for a car on an amusement park ride is given as v = At2 + Bt with constants A = 2.9m/s3 and B = 1.3m/s2. If the car starts at the origin, what is its position at t = 4.2s?

A ball is tossed vertically upward with an initial speed of 18.2 m/s. How long does it take before the ball is back on the ground? (Assume the ball is tossed upward from the ground.)

An airplane starts from rest and accelerates at 11.5m/s^2. What is its speed at the end of a 655m runway?

A ball spins on a 0.5m-long string with a speed of 3.8m/s. Calculate the acceleration of the ball.

The position of a particle moving along the x axis is given by x = (21 + 22t − 6t^2)m, where t is in s. What is the average velocity during the time interval t = 1s to t = 3s?

A rock is thrown downward from an unknown height above the ground with an initial speed of 10m/s. It strikes the ground 3s later. Determine the initial height of the rock above the ground.

A ball thrown vertically from ground level is caught 3s later when it is at its highest point by a person on a balcony which is 14 m above the ground. Determine the initial speed of the ball

A race car moving with a constant speed of 60 m/s completes one lap around a circular track in 50 s. What is the magnitude of the acceleration of the race car?

Sorry , I'm new user to jiskha

Let = 2 î + 3 ĵ and = 2 î - 2 ĵ. Find the magnitude of the following. (a) Eand F (b) E+F (c) -E – 2F

very helpful information. I need a teacher like you.

A race car moving with a constant speed of 60 m/s completes one lap around a circular track in 50 s. What is the magnitude of the acceleration of the race car?

how do I solve for these two physics questions #1on the top and #2 on the bottom

Henry do I use the same equation to solve for #2 too or it is just for #1?

i need the answers for unit 3 lesson 18

Kid is rong trust me

the real answers are 1C 2C 3B 4D 5B 6C 7C 8D 9 D 10 A 11 B 12A 13C 14A 15A 16C 17B i do not lie but make shure it is the write test pleas

thank you so much thank you
