Question

At an air show, a jet plane has velocity components

vx= 635km/h and vy= 430km/h at time 3.90s and vx= 938km/h and vy=385km/h at time 6.62s.

A) For this time interval, find the x component of the plane's average acceleration. (km/h2)

B) For this time interval, find the y component of the plane's average acceleration. (km/h2)

C) For this time interval, find the magnitude of its average acceleration. (km/h2)

D) For this time interval, find the direction of its average acceleration. ?clockwise from +x axis

Explanation / Answer

Part A)

Apply vf = vo + at

938 = 635 + a(6.62-3.9)/3600

a = 4.01 X 10^5 km/hr^2

Part B)

385 = 430 + (a)(6.62-3.9)/3600

a = -5.96 X 10^4 km/hr^2

Part C
net^2 = (4.01 X 10^5)^2 + (5.96 X 10^4)^2

net = 4.05 X 10^5 km/hr

Part D)

tan(angle) = 5.96 X 10^4/4.01 X 10^5

angle = 8.45 degrees
