Two parts: a) An object with an initial mass mi=7and an initial velocity vi=6m/s making an angle of 40 degrees with the +x axis has, after a time 4 seconds, final velocity vf=3making an angle of 0 degrees wrt -x. a) Determine the net force acting on the mass corresponding to Fnet=(pf-pi)/delta(t), needed to produce that change in momentum. b) Now, assuming there is gravity plus a second, contact force acting on the mass, estimate the magnitude of the second...

An object is thrown upward with an initial velocity of 32.1 m/s. When the object reaches it maximum height, it is true of the acceleration, a, and the velocity, v, that: both its acceleration and velocity are zero both its acceleration and velocity change sign velocity is equal to zero, but acceleration is not acceleration is equal to zero, but velocity is not None of the above. Please help. Only one answer is true. Please give reason why.

An object is initially traveling at a velocity of 12 m/s. It then begins to change it’s velocity according to the function ?=2.5?+3? v = 2 . 5 s + 3 a , where v is the velocity of the object, s is the objects position, and a is the acceleration. Determine the velocity of the object 30 meters after the velocity begins to change. (17.5 m/s)

When you shine a light on an object, the momentum from the photons that make up that light impacts the object. For macroscopic objects, this will have no measurable effect. Describe why this is different for atomic-sized objects. Suppose you shine a very long wavelength light on one electron and a very short wavelength light on another electron. What differences will you observe? Why does shining very short wavelength photons on an electron not tell you exactly where the electron...

When a car is traveling under uniformly accelerated motion, its linear momentum is conserved 2. For a car turning in a sharp turn with a constant speed of 60 mph, its total acceleration is equal to 0. 3. If a body is undertaking fixed axis rotation, a point that matches the axis of the rotation will have linear velocity equal to zero. 4. If a body is undertaking fixed axis rotation, a point that matches the axis of the rotation...
