Using the appropriate equation of motion, determine… the maximum height of the ball above the bat. the time it takes for the ball to reach its highest point. Given that a baseball has a mass of 145 g, determine… the kinetic energy of the ball when it left the bat. the potential energy of the ball at its highest point. algebraic Light and atoms lecture tutorial answers

It’s total velocity is found by adding the horizontal and final vertical components of the velocity to find the resultant. c 2 = a 2 + b 2 = (8.0m/s) 2 + (17m/s) 2 c = 19m/s. tanΘ = opp/adj = (8.0m/s) / (17m/s) Θ = 25° The object is moving at 19m/s at an angle of 25° below the horizontal when it hits the ground.

on a block that lies on a frictionless floor. If the force magnitudes are chosen properly, in which situation it is possible that the block is (a) stationary and (b) moving with constant velocity? a y≠0 a=0 a y≠0 a=0 F net F net Q5. In which situations does the object acceleration have (a) an x-component, (b) a y component? (c) give the ... Enochian magic pdf

Block C starts from rest at t 0 and moves downward with a constant acceleration of 4 in./s 2. Knowing that block B has a constant velocity of 3 in./s upward, determine (a) the time when the velocity of block A is zero, (b) the time when the velocity of block A is equal to the velocity of block D, (c) the change in position of block A after 5 s. This block, as well as a second block of mass 0.225 kg is at rest on a frictionless floor. The spring is then released suddenly and the 0.180 kg block slides to the right, detaching from the spring, and then collides with the other block, sticking to it. Velcro 0.180 kg frictionless 0225 kg (a) (8) Calculate the final velocity of the joined blocks.

(b) A cathode-ray oscilloscope (c.r.o.) is used to determine the frequency of the sound emitted by a loudspeaker. The trace produced on the screen of the c.r.o. is shown in Fig. 4.1. 1 cm 1 cm Fig. 4.1 The time-base setting of the c.r.o. is 250 µs cm–1. Show that the frequency of the sound wave is 1600 Hz.

Flow rate and velocity are related, but quite different, physical quantities. To make the distinction clear, think about the flow rate of a river. The relationship tells us that flow rate is directly proportional to both the magnitude of the average velocity (hereafter referred to as the speed) and the size of a river...

v = dx/dt = - A sin ( t + ) a = dv/dt = d 2 x/dt 2 = - A 2 cos ( t + ) Now we can look at the directions. Displacement and velocity will sometimes be in the same direction and sometimes in opposite directions. Velocity and acceleration will sometimes be in the same direction and sometimes in opposite directions. Mar 14, 2010 · So the block of mass m is given a velocity, v=5m/s. Its kinetic energy is = (1/2)mv^2. As the block goes up the slope its kinetic energy is converted to gravitational potential energy = mgh. When the block comes to rest upon the slope all the KE has converted to GPE. Thefore the inital KE is equal to the final GPE. So (1/2)mv^2 = mgh. the ...

Because the bullet sticks in the wooden block, the final momentum is the product of the total mass, m1 + m2, and the final velocity of the bullet/wooden block combination: pf = (m1 + m2) vf Because of the principle of conservation of momentum, you can say that Feb 01, 2020 · c. 0.21 m/s d. 0.28 m/s 619. A bullet weighing 0.014 kg and moving horizontally with a velocity of 610 m/s strikes centrally a block of wood having a mass of 4.45 kg which is suspended by a cord from a point 1.2 m above the center of the block.
