Two 100kg blocks are stacked on top of eachother. The coefficient of friction between the bottom block and the ground is 0.350 and the coefficient of static friction between the top block and the bottom block is 0.700. Will a 85kg man be able to push the blocks forward without the top block falling onto him if he applies 300. N to the bottom block?

This figure shows a person preparing to do a pushup. Calculate the back extensor force (Fm) required to keep the trunk in the static position as shown. Report Fm, in units of N, to 0 decimal points (e.g. 101 N). Report only positive values (i.e. the absolute value). You are allowed an error margin of +/- 10 N from the exact correct answer. The spine and back extensor muscle (Fm) are aligned horizontally with the floor. The ground reaction force (GRF) under the hand is aligned vertically. You only need to consider the weight of the trunk (disregard the head and arms). Here is information you may need to solve this problem: • The GRF is 195 N. • The GRF has a moment arm of 0.4 m relative to the vertebra axis of rotation. • The weight of the trunk is 303 N. • W trunk has a moment arm of 0.29 m relative to the vertebra axis of rotation. • Fm has a moment arm of 0.06 m relative to the vertebra axis of rotation.
Billy and Timmy are using a ramp to load furniture into a truck. While rolling a 250-pound piano up the ramp, they discover that the truck is too full of other furniture for the piano to fit.Timmy holds the piano in place on the ramp 20 o while Billy repositions other items to make room for it in the truck.If the angle of inclination of the ramp is how many pounds of force must Timmy exert to hold the piano in position?
Hi I needed help with this. An athlete with a mass of 53.5 kg is doing pushups as shown in the figure below. The value for rW⊥ is 1.00 m and the value for rR⊥ is 1.60 m. (a) Assuming she moves upward at a constant speed, determine the force she must exert on the floor with each hand to do a push-up.(b) The triceps muscle in the back of her upper arm with an effective lever arm of rT⊥ = 1.70 cm, as shown in the figure below, and she exerts force on the floor a horizontal distance of r 'R⊥ = 2.05 cm from the elbow joint. Determine the force in the triceps muscle.In order to appreciate the strength of the triceps, determine the ratio of the force in the tricep muscle to her weight (in decimal form). FT/W = ?
