Practice NCEA Level 1 Acceleration in the app →Acceleration is defined as the rate of change of which quantity?How is average acceleration calculated from velocity and time?How does instantaneous acceleration differ from average acceleration?What does it mean for an object to have constant acceleration?On an axis where the positive direction is fixed, what does a negative acceleration component mean?A subway train accelerates from rest to 30.0 km/h (8.333 m/s) in 20.0 s. What is its average acceleration?At the end of its trip, the same subway train slows from 30.0 km/h (8.333 m/s) to a stop in 8.00 s. What is itA cheetah accelerates from rest to a speed of 30.0 m/s in 7.00 s. What is its acceleration?A woman backs her car out of her garage with an acceleration of 1.40 m/s^2. How long does it take her to reachA dragster crosses the finish line at 140 m/s, having accelerated at a constant rate the whole way from rest. A dragster accelerates from rest at 26.0 m/s^2 over a quarter mile (402 m). What is its final velocity?A class of dragsters can reach a top speed of 145 m/s in only 4.45 s from rest. What average acceleration doesAn Olympic-class sprinter starts a race with a constant acceleration of 4.50 m/s^2. What is her speed 2.40 s lIf a dragster accelerates at a rate of 39.2 m/s^2, how many g's (using g = 9.80 m/s^2) does the driver experieA rock is thrown straight up from a cliff edge with an initial velocity of 13 m/s. Taking up as positive and uThe same rock is thrown straight up from a cliff edge at 13 m/s. Taking up as positive and using g = 9.80 m/s^A girl drops a pebble from rest off a high cliff. It falls for 2.00 s before hitting the water below. Using g The driver of a sports car travelling at 10.0 m/s presses the accelerator for 5.0 s, raising the speed to 30.0A girl rolls a basketball with an initial velocity of 2.0 m/s. It decelerates at a rate of -0.20 m/s^2 and rolA swan on a lake must reach 6.00 m/s to take off. Starting from rest, it accelerates at a constant 0.350 m/s^2A swimmer bounces straight up off a diving board with an initial upward velocity of 4.00 m/s, from a takeoff pA velocity increases from 0 to 20 m/s over 10 s at a constant rate. What is the average acceleration?How long does it take to accelerate from 8.0 m/s to 20.0 m/s at a constant rate of 3.0 m/s^2?A bullet is accelerated from the firing chamber to the end of the barrel at an average rate of 6.30 x 10^5 m/sA car accelerates from rest at a stop sign at 3.0 m/s^2 up to 21.0 m/s, then immediately decelerates at 4.0 m/A ball is thrown straight up at an initial velocity of 15.0 m/s. It passes a tree branch on the way up at a heA racecar rounds a curve at a perfectly constant speed. Why is it still considered to be accelerating?A skydiver jumps from a plane, and the positive direction is taken as downward. Which kinematic equation wouldAn object falls from rest for 2.0 s, at which point it is still 60 m above the ground. Which order of kinematiIf a plot of displacement versus time is a straight line, what does that say about the object's acceleration?Under what condition is a velocity versus time graph a straight line rather than a curve?An object starts from rest and moves with constant acceleration. Which pair of statements about its displacemeFor an object falling under constant gravity, which pair of graphs against time are straight lines?During launch and reentry, about how many g's does the space shuttle produce for its occupants?Drag racers compete over a standing start on a track of what length?
