The defiant starship accelerates at 121.4 m/s^2 at an angle of 192⁰ from east. Determine the x and y components of this acceleration?

A person walks 2.80 km north and then 2.00 km east, all in 2.20 hours.   (a) What is the magnitude (in km) and direction (in degrees north of east) of her displacement during the given time? (b) What is the magnitude (in km/h) and direction (in degrees north of east) of her average velocity during the given time?(c) What was her average speed (in km/h) during the same time interval?

A place-kicker must kick a football from a point of 36.0 m ( about 40 yards) from the goal.  Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 23.9 m/s at an angle of 51.5 degrees to the horizontal.  So in step 3 use an equation for the  y-component of displacement under constant acceleration to find the height of the ball at this time, where yo is the initial vertical displacement, voy is the initial y-component of velocity, and ay is the vertical acceleration. y=yo+voy^t+1/2ayt^2. Use trigonometry.

At the beginning of a 3.0-h plane trip, you are traveling due north at 192 km/h. At the end, you are traveling 239 km/h in the northwest direction (45° west of north). What is the magnitude of your average acceleration during the trip? answer in km/h^2

Initially, a particle is moving at 5.45 m/s at an angle of 38.5 above the horizontal. Four seconds later, its velocity is 6.24 m/s at an angle of 54.3 below the horizontal. What was the particle's average acceleration during these 4.00 seconds in the x-direction (enter first) and the y-direction?

An airplane starts at rest and accelerates at 8.4 m/s^2at an angle of 35 degrees south of west. After 11 s, how far in the westernly direction has the plane traveled? After 11 s how far has the plane traveled in the southernly direction?

A particle leaves the origin with an initial velocity 3.00î m/s and a constant acceleration ở -1.00î – 0.50ĵ m/s². When it reaches its maximum x coordinate, what are its (a) velocity and (b) position vector?

An object is thrown straight upward with an initial velocity of 11.7 m/s. What is the object's maximum upward displacement? Enter a number assuming proper SI Units.

In reaching her destination, a backpacker walks with an average velocity of 1.48 m/s, due west. This average velocity results, because she hikes for 6.55 km with an average velocity of 2.75 m/s, due west, turns around, and hikes with an average velocity of 0.513 m/s, due east. How far east did she walk?

The initial velocity of a car is 35 m/s due North.  Its final velocity is 42 m/s at 15 degrees South of East.  If this takes 30 seconds, what is the magnitude and direction of the car's average acceleration?
