A frictionless pendulum of mass m=1 kg and length L=1 m, gets released at t=0 from a distance x=0.12 m relative to its equilibrium position. м M What is the velocity of the pendulum's mass at time t=1.5 s? Give your answer in units of [m/s] and up to 1 decimal place (e.g. 0.6)

Q19. A wooden block of mass mı sits on a floor attached to a spring in its equilibrium position. A bullet of mass m2 is fired with a velocity of v into the wooden block, where it remains. Derive an equation for the maximum displacement of the spring if the floor is frictionless and the spring has a spring constant 1 of k. (x = m2v k(m1+m2)'

A block of mass m2 = 7.5 kg, at rest on a horizontal surface that has negligible friction, is connected to a spring which is initially not stretched or compressed. The other end of the spring is fixed to a wall, and the spring constant is k = 180 N/m. Another block of mass m1 = 4.5 kg and speed v1=3.3 m/s collides with the 7.5 kg block. The blocks stick together, and compress the spring. What is the maximum compression of the spring?

Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s not cm/s). Answer must be in standard form scientific notation. All angles are to be calculated to the nearest 0.1 deg (tenth of a degree).

A 1-kilogram mass X and a 2-kilogram mass Y are pushed together against a spring and tied with a cord.When the cord breaks, the 1-kilogram mass X moves to the right at 5.92 m/s.What is the velocity of the 2-kilogram mass Y? A zero B 2.96 m/s to the left 11.84 m/s to the left D 11.84 m/s to the right E 2.96 m/s to the right

A bowling ball is attached to a 2.91-meter long cable and hung from the ceiling. The cable is kept taut and the ball is raised to an initial height of 1.73 meters above the classroom floor. It is released from rest and allowed to swing as a pendulum. Determine its speed (in m/s) when it is at a height of 1.17 meters above the floor.

2. A simple pendulum is suspended from the ceiling by means of a string. this time of length 2.33 m, which you release from rest at an angle of 45.4 degrees to the vertical. What will be the speed of the pendulum at the instant it reaches an angle of 36.3 degrees above the vertical?      2.18 m/s      3.69 m/s      2.98 m/s      5.17 m/s

A conical pendulum has length l and the angle made by the string with vertical is e = 35° . The mass of the object is m=124 g. If the speed of the object is v=3.9m/s find the length of the string. Take g=10Om/s2. Round your answer to one decimal place.

A 3 kg mass is fastened to the end of a spring with a spring constant of 109 N/m. The mass position is given by x(t)=Acos(omega*t), with A=0.22 m. What is the mass's maximum speed in m/s? Give your answer to three significant figures.

The displacement of an oscillating mass is given by x(t) = 30 cos( 2 t ). At time t = 2π s, what is the velocity of the mass in m/s?
