Aconical pendulum is formed by attaching a 50g mass to a 1.2m string. the mass swings around the circle of radius 25cm (a) calculate the speed of the mass (b) acceleration of the mass (c) tension in the string

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Will you chech and finish these for me, because i am stumped with them.

Hey student studies gravity using objects that have the same mass which two objects have the greatest gravitational force acting between them a. 100kg 1.0m 100kg b. 100kg 2.0m 100kg c. 100kg 2.0m 100kg big d. 100kg big 3.0m 100kg big
