A hockey puck moves 28 meters southward, then 14 me northward, and finally 4 meters southward.

At noon a car is driving west at 55 km/h. At the same time, 15 km due north another car is driving south at 85 km/h. At what time are the two cars closest, and what is the distance between them?

If an airplane is flying at 140 miles per hour east and turns in a smooth curve with a diameter of 3 miles, what is its centripetal acceleration in m/s2 ?  SYW!!!

An airplane has an air speed of 267 miles per hour and a compass heading of 140°. A steady wind of 54 miles per hour is blowing in the direction of 183°. What is the plane's true speed relative to the ground? What is its compass heading relative to the ground? W. 270° ... The groundspeed is miles per hour. (Round to the nearest integer as needed.) 270 240 300 320 072 N, 0° 340 1 opz 081 091 S, 180° 09 90 1 100 120 140 E, 90°

ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. A train is travelling east along a straight run of track at 66 km/hr. Inside, two siblings 2.2 m apart are playing catch directly across the aisle. The kid wearing a PJ Harvey T-shirt throws the ball horizontally north. The ball crosses the train and is caught 1.2 s later by their little sibling. (Ignore any effects of gravity or friction.) Find the magnitude of the ball's velocity in m/s from the little brother's point of view. What is the magnitude of the velocity (in m/s) of the ball as seen by someone standing still outside the train? What is the angle (in degree) that a stationary observer would say the ball makes during the throw, relative to the direction of the train?

The Incredible Hulk, chased by the army, leaps with speed 16_m/s at a 48° angle above the horizontal from the top of a building. If he lands 55_m from the base of the building, then find the height of the building. 59.28_m 55.22_m 64.87_m 70.72_m 68.23_m O 62.38_m

If a ping pong ball launcher is at a 45 degree angle and the distance it travels is 1.2 meters. How high does the ping pong ball reach?

A car is traveling at a speed of 190 km/hr on a circular racetrack of radius 850 m.  What is its centripetal acceleration in m/s2?
