Question

A 1700 kg car is initially travelling north at 22m/s. The driver then completes a 90°turn toward the east in a 4.4s without changing the car’s speed. What is the magnitude of the average force that acted on the car during the entire turn?

A.1.2×10^4N

B.0.0N

C.1.4×10^4N

D.8.5×10^3N

E.1.7×10^4N

Answer 1

Answer #1

A North East mass m = 1700 kg Let east is represented by Xasis and north is represented by Yases - then initial velocity ū=
