A 50kg mass is tied to a massless rope wrapped around a solid cylindrical drum, mounted on a frictionless horizontal axle. When the mass is released, it falls with acceleration 3.9m/s2 .
(a) Find the rope tension.
(b) Find the drum's mass.
The acceleration due to gravity on the surface of the moon is about g/ 6. If a pendulum has a period T on earth what will its period be on the moon?
A highway curve with a radius of 555 m is banked properly for the car travelling 150 km/h. If a 1650 kg Porshe 928 S rounds the curve at 220 km/h, how much sideways force must the tires exert against the road if the car does not skid.
Illustrate what management's role in addressing these challenges. Illustrate what type of information technology would increase production?
A 46kg box is being pushed a distance of 7 m across the floor by the force vector P whose magnitude is 144N. The force vector P is parallel to the displacement of the box.
