The takeoff speed for this plane will be 70 m/s. Assuming this minimum acceleration, what is the minimum
allowed length for the runway?
is a constant and v is the speed of the car at an instant. I need to find the speed of the car as a function of time.
Starting from rest, a 3.5 kg object is acted upon by an unbalanced force and acquires a speed of 14.0 m/s after moving a distance of 35 m. Find a.) the acceleration of the object; b.) the unbalanced force acting on the object, and c.) the time it takes for the object to attain a speed of 14. 0 m/s

(b)What is the speed of the elevator at t = 3.15 seconds?
(a) What is the speed of the ball?
(b)When is the ball at 10.0 m on the X axis?
(c) When the ball has position of 10.0 meters on the X-axis, what is the position on the Y-axis?
a 40,000 kg airplane is provided with 130,000N of thrust by its engines as it takes of at an angle of 25 degrees above the horizontal. If the velocity of the airplane is constant, how much upward force on it is provided by its vertical component
a certain particle has lifetime of 2.2us when measured at rest. how fat does it goes on average before decaying if its speed is 0.99cwhen it's created
