You pick up a barbell with weights (total mass: 100.0 kg) from ground to approximately 0.800 m above the ground (roughly equivalent to doing a deadlift). Once it has been lifted, you then carry it 10.0 m at a steady speed before stopping and finally gently lowering the barbell back to the ground. How much work have you done on this barbell, in J?

An athlete with a mass of 70 kg is performing a barbell back squat exercise with a load of 150 kg. From the starting position (position A), the athlete stands still prior to lowering their COM in the negative vertical direction at a rate of -1.45 m/s2 (position B). Once they reach the bottom position, they hold the squat for 3 seconds (e.g. 0 m/s2 – position C). After the 3 second period, the athlete raises their COM in the...

A power lifter performs a dead lift, raising a barbell with a mass of 305 kg to a height of 0.42 m above the ground, giving the barbell 1256.66 J of potential energy. The power lifter then releases the barbell, letting it drop towards the ground. Determine the magnitude of the vertical velocity of the barbell when it reaches a height of 0.21 m (on the way down) using a mechanical energy approach. Then calculate the velocity right as it...

At an angle of 36.5deg with the horizontal, a ladder, with mass (m = 100.0 kg) rests on a frictionless wall and on the ground with a friction coefficient (μS). a) What is the minimum value of the ladder-ground static friction coefficient if the ladder’s center of mass is located at a distance, 1/3 of its total length? b) A boy, with mass (m = 45.0 kg), uses the ladder to retrieve a bag of 5 basketballs, each with mass...

A weightlifter stand on bathroom scale anf pumps a 5kg barbell up and down. Her mass is 60kg. A) what is her reading on the bathroom scale ? B) she throws the barbell up with an acceleration of 0.5 m/s^2. What is the reading of the scale as the barbell leaves her hand ?

A crate of mass 100.0 kg rests on a rough surface inclined at an angle of...

A crate of mass 100.0 kg rests on a rough surface inclined at an angle of 37.0° with the horizontal. A massless rope to which a force can be applied parallel to the surface is attached to the crate and leads to the top of the incline. In its present state, the crate is just ready to slip and start to move down the plane. The coefficient of friction is 80% of that for the static case a. What is the...

Two metal disks, one with radius ?1 = 2.50 cm and mass ?1 = 0.800 kg and the other with radius ?2 = 5.00 cm and mass ?2 = 1.60 kg are welded together and mounted on a frictionless axis through their common center as shown to the right. a) A light string is wrapped around the edge of the smaller disk and a 1.50 kg block is suspended from the free end of the string. How far will the...

Two uniform solid spheres, each with mass 0.800 kg and radius 8.00×10−2 m, are connected by a short, light rod that is along a diameter of each sphere and are at rest on a horizontal tabletop. A spring with force constant 157 N/m has one end attached to the wall and the other end attached to a frictionless ring that passes over the rod at the center of mass of the spheres, which is midway between the centers of the...

You push a box of mass 19.1 kg with your car up to an icy hill slope of irregular shape to a height 5.9 m. The box has a speed 12.9 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before sliding into a box larger box of mass 13 kg. The boxes then fall off a sheer cliff together to the...

You push a box of mass 17.4 kg with your car up to an icy hill slope of irregular shape to a height 5.1 m. The box has a speed 11.8 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before elastically colliding with a smaller box of mass 12 kg. The boxes then fall off a sheer cliff individually to the...
