Q. A 1 m long pedulum with a 2kg mass is pulled back 0.1m and after that released, so that it swings back and forth. How did they solve T= 2.007 seconds?
Q. At time a grinding wheel has an angular velocity of 27. It has a constant angular acceleration of 33 until a circuit breaker trips at time = 1.7. From then on, the wheel turns through an angle of 433 as it coasts to a stop at constant angular deceleration.
A truck travels beneath an airplane that is moving 190 km/h at an angle of 26? to the ground.
A ballplayer catches a ball 2.75 seconds after throwing it vertically upward. With what speed did he throw it? Calculate the final & resultant velocity and acceleration.
What happens in the table as to the potential energies
What is your displacement after running 2.60 west on Strawberry Fields, 1.1 south on Penny Lane, and 5.0 north of east at 40 degree on Abbey Road.
What type of car was involved in the hit and run
The electric field everywhere on the surface of a thin spherical shell of radius 0.780m is measured to be equal to 940 N/C and points radially toward the center of the sphere.
Describes possible scenarios among following
Examine whether it is reasonable to ignore the effects of gravity for each particle. Evaluate the paths travelled by electron and proton and explain the differences.
Find out total vector displacement
At rest when constructed, the ring is set rotating about its axis so that the people inside experience effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the r..
Two freight cars, each with a mass of 2.9 x 10^5 kg, collide and stick together. One was initially moving at 2.80 m/s and the other was at rest. What is the final speed.
Calculate the magnitude, the direction of resultant force and the coefficient of kinetic friction.
