If the particle maintains the same acceleration, its speed after 100 seconds is?

A “car” is sent a up tilted air track.  If the initial speed is 0.43 m/s, how high in mm will the car rise vertically from where it started? Can you help with a visual aid; and then the mechanics of calculation.

A car traveled up a hill at a constant speedof 10 m/s  and then re down the hill at  20m /s. If the time to turn around is ignored,(a) What was the average speed for the trip?(b) What was the average acceleration for the trip?

Hi, I need help with this physcis problem. I've gone over it multiple times and can't firgure it out. Anyway you can help?   A car, initially at rest, accelerates at a constant rate of 2 m/s2 due east (choose east as the positive direction; round your answer to the nearest meter per second; include units)What is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? What is its velocity after 4 seconds? What is its velocity after 5 seconds? What is its velocity after 9 seconds?  If instead a car accelerates at a constant rate of 5 m/s2 due eastWhat is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due westWhat is its velocity after 1 second?

Plssss help, ignore the writing, determine the object's acceleration at t=4s

How much time is required for a particle to slow from 32m/to 22 m/s over a distance of 68 m if the acceleration is constant? Round the answer to two decimal places.
