    Please help with this question: A plane travels a distance of 140 km due west of Vancouver International Airport. It then travels 60 km at a bearing of 340 degrees. How far from the Airport is the plane? Thank you for all your help.

    If a plane takes off on runway 31 (N 31o W) and flies 4 miles, then makes a right (90o) turn and flies 11 miles, what bearing will the traffic controller use to locate the plane?

    An 8kg block starts from rest from the top of a plane, inclined at 40o with respect to the horizontal, and slides down at a constant acceleration. If the coefficient of kinetic friction between the block the plane is 0.35 determine how far the block

    The block shown in (Figure 1) has mass m = 7.0 kg and lies on a fixed smooth frictionless plane tilted at an angle θ = 22.0 ∘ to the horizontal. If the block starts from rest 15.2 m up the plane from its base, what will be the block's speed when it

    If an airplane directly north at 2000 km/hr and there are 50 mph/hr winds blowing west. whis is the actual path of the plane seen from someone on the ground? What is the ground speed of the plane in mph?

    A plane starts from rest at the end of a runway and requires 200.0 km/h for takeoff . If it takes 30.0 a to reach takeoff speed, what acceleration must the plane's engines provide to get off the runway ?
