Abaseball slugger hits a pitch and watches the ball fly into the bleachers for a home run, landing h = 9.5 m higher than it was struck. when visiting with the fan that caught the ball, he learned the ball was moving with final velocity vf = 33.9 m/s at an angle θf = 28° below horizontal when caught. assume the ball encountered no air resistance, and use a cartesian coordinate system with the origin located at the ballʼs initial position. part (a) create an expression for the ball’s initial horizontal velocity, v0x, in terms of the variables given in the problem statement. b) calculate the ball’s initial vertical velocity, v0y, in m/s. part (c) calculate the magnitude of the ball’s initial velocity, v0, in m/s. part (d) find the angle θ0 in degrees above horizontal that the ball left the bat.

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
