A mass m is moving on a frictionless, horizontal surface. At t = 0, the mass is moving to the right at velocity vo. What is the velocity of the mass (magnitude and direction) after a force F directed to the right has been applied for a time t? Answer: O True O False Uf = Ft m mvo

A block with a mass of m = 16 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x-direction with a magnitude of F1 = 8.5 N. The second has a magnitude of F2 = 19.5 N and acts on the body at an angle θ = 11° measured from horizontal, as shown. a.) Write an expression for the component of net force, Fnet,x, in the x-direction, in terms of the variables given in the problem statement. b.) Write an expression for the magnitude of the normal force, FN, acting on the block, in terms of F2 and the other variables of the problem. Assume that the surface it rests on is rigid. c.) Find the block's acceleration in the x-direction, ax, in meters per second squared.

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

A particle of mass m moving along the x-axis experiences the net force Fx=ct, where c is a constant. The particle has velocity v0x at t = 0. Find an algebraic expression for the particle's velocity vx at a later time t. Express your answer in terms of the variables c, t, v0x, and m.

Block 1 with mass 66 kg is sitting on a horizontal frictionless surface as shown below. It is attached to a string of negligible mass that goes over a pulley with negligible mass and negligible friction. The other end of the string is attached to block 2 with mass 254 kg.

An object of mass 0.77 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 12.7 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval. (Enter a number.) N

A frog with some sort of little monster on his back is swimming in a bathtub of split tomato soup. The frog's mass is m1 = 0.0280 kg, and the monster's mass is m2 = 0.0300 kg. The frog propels the monster and himself forward with a constant force of F = 0.440 N and accelerates at a constant rate of a = 2.65 m/s^2.  a) What is the resistive force of the split tomato soup on the frog? b) If the frog starts at rest at one side of the bathtub and swims across its length in t = 1.91 s, how long is the bathtub? c) How much work is done by the split tomato soup on the frog?

Two objects (m1=11.0 kg and m2=3.00 kg) are separated by 40.0 cm. A third object (m3=1.00 kg) is placed at a location along the line connecting them such that the net force acting on it is zero. By considering the force vectors, this location must be between the two original objects. We will define x as the distance between m1 and m3 and y as the distance between m2 and m3.   1) Find the distance between 11.0-kg object and 1.00-kg object along the line AB where a small, 1.00-kg object could rest such that the net gravitational force on it due to the two objects shown is exactly zero. (Express your answer to two significant figures.)
