At the equator, the radius of the Earth is approximately 6370 km. A plane flies at a very low altitude at a constant speed of v = 278 m/s. Upon landing, the plane can produce an average deceleration of a = 21 m/s2.
What is the numeric value for the minimum landing distance, d (in meters), this plane needs to come to rest? Assume that when the plane touches the ground it is moving at the same speed as it was when it was flying.
A car drives around a circular track of diameter 161 m at a constant speed of 47.4 m/s. During the time it takes the car to travel 256 degrees around, what is the magnitude of the car s average acceleration?
Hint: Do not calculate instantenous accelleration. Instead calculte the average acceleration over the fraction of a complete lap. Average acceleration equals change in velocity divided by change in time, and that this is a two-dimensional situation so you'll have to calculate the x and y components of the average acceleration first and then figure out the magnitude. Remember also that ax = Δvx/Δt and ay = Δvy/Δt.
0 m/s^2
27.91 m/s^2
13.96 m/s^2
9.84 m/s^2
An object is moving with an initial velocity of 5.8 i m/s and a final velocity 13.8 i m/s. The time taken for acceleration is 2.2 seconds. Calculate the acceleration in m/s2 to 2 sf.
In your answer, you do not enter the i unit vector, but you do need to enter negative signs, if appropriate.
e.g. if your answer is a = -5.4 i m/s,2 you would enter -5.4
