A spacecraft is traveling with a velocity of v0x = 6710 m/s along the +x direction. Two engines are turned on for a time of 796 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 2.31 m/s2, while the other gives it an acceleration in the +ydirection of ay = 8.98 m/s2. At the end of the firing, what is a) vx and b) vy?

A spacecraft is traveling with a velocity of v0x = 5460 m/s along the +x direction. Two engines are turned on for a time of 854 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.20 m/s2, while the other gives it an acceleration in the +y direction of ay = 8.60 m/s2. At the end of the firing, find the following.(a) vx =  m/s(b) vy =  m/s

the earth is approximately 1.5x10^8 km from the sun. how many minutes does it take light to travel from the sun to the earth? light travels at a speed of 3.00 x10^10 m/s

On a spacecraft two engines fire for a time of 389 s. One gives the craft an acceleration in the x direction of ax = 3.41 m/s^2, while the other produces an acceleration in the y direction of ay = 7.34 m/s^2. At the end of the firing period, the craft has velocity components of vx = 1860 m/s and vy = 4290 m/s. Find the (a) magnitude and (b) direction of the initial velocity. Express the direction as an angle with respect to the +x axis.

Any assistance with this physics problem would be great!

When a train is traveling along a straight track at 2m/s, it begins to accelerate at a = (60v-4) m/s, where v is in m/s. Determine its velocity v and the position 3 sec after the acceleration.

The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.40 m above the floor. The ball hits the floor 0.160 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?     54.7 m/s^2     82.1 m/s^2     207.9 m/s^2     109.4 m/s^2

An object moves on xy plane according to the equation 7 = 20 cos(3t) î + (1,5t + 3,5t2)j. Determine its position at t = 0. Find its average velocity and average acceleration between t = 2s and t = 5s.

A bowling ball traveling with constant speed hits the pins at the end of a bowling lane 16.5 m long. The bowler hears the sound of the ball hitting the pins 2.61 s after the ball is released from his hands. What is the speed of the ball (in m/s), assuming the speed of sound is 340m/s?

A spacecraft starts from rest, and makes a journey to a destination 220000 km from its starting point. It does so by accelerating at a constant rate of 7.51 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 7.51 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?
