Question

A jet plane is flying at a constant altitude. At time t_{1} = 0 it has components of velocity v_{x} = 95m/s , v_{y} = 112m/s . At time t_{2} = 35.0s the components are v_{x} = 163m/s , v_{y} = 42m/s (a) For this time interval calculate the average acceleration. Give your answer as a pair of components separated by a comma. For example, if you think the x component is 3 and the y component is 4, then you should enter 3,4. Express your answer using two significant figures.?? (b) Find the magnitude of the average acceleration. Express your answer using two significant figures.? (c) Find the direction of the average acceleration (let the direction be the angle that the vector makes with the +x-axis, measured counterclockwise).

Explanation / Answer

ax = (163-95 )/35 = 1.94 m/s^2 ay = (42-112)/35 = -2 m/s^2 a=(1.94 , -2) magnitude of accelearation = 2.78 m/s^2 direction = 314.13 degrees in counter clock wise with + x axis
