An insect called the froghopper ( Philaenus spumarius ) has been called the best juniper in the animal kingdom. This insect can accelerate at over 4.0 × 10 3 m/s 2 during a displacement of 2.0 mm as it straightens its specially equipped “jumping legs.” (a) Assuming uniform acceleration, what is the insect's speed after it has accelerated through this short distance? (b) How long does it take to reach that speed? (c.) How high could the insect jump if air resistance could be ignored? Note that, the actual height obtained is about 0.70 m, so air resistance is important here.

An object is subject to a constant acceleration of 4.16 m/s2 in the positive x direction. If it is initially at rest, what is its displacement in the x-direction at t = 8.99 s?
A jet plane comes in for a landing with a speed of 100 m/s, and its acceleration can have a maximum magnitude of 5.00 m/s^2 as it comes to rest, from the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest?
If the car’s speed decreases at a constant rate from 70 mi/hmi/h to 40 mi/hmi/h in 3.0 ss, what is the magnitude of its acceleration, assuming that it continues to move in a straight line?
