A 70.0 kg skydiver falls toward the earth. The force due to air resistance is 1200N. What is the accelaration of the skydiver? I got 7.34 m/s. Can you help me with this.
In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.
The CERN particle accelerator is circular with a circumference of 7.0 km. (a) What is the acceleration of the protons (m=1.671027kg)that move around the accelerator at 5of the speed of light? (The speed of light is v=3.00108m/s .) (b) What is the force on the protons?
I am mostly just wondering about finding the velocity B. I know how to find tension after that. I got Vb= 4.214 m/s for the veloctity but I am not sure if I did it right. Hight initial is 0.702 m This was what I did (1/2)(5)(2^2)+(5)(9.8)(.702)=(1/2)(5)(Vf^2)

A 1.9-kg block slides down a frictionless ramp. The top of the ramp is h1= 1.9 m above the ground; the bottom of the ramp is h2 = 0.50m above the ground. The block leaves the ramp moving horizontally, and lands a horizontal distance d awayWhat is the Distance (d)?
The acceleration due to gravity on Earth differs slightly from place to place, depending on topography (e.g., whether you areon a hill or in a valley) and subsurface geology (whether there is dense rock like iron ore as opposed to light rock like saltbeneath you.) The precise acceleration due to gravity can be calculated from data taken in an introductory physicslaboratory course. An object, usually a metal ball for which air resistance is negligible, is dropped and the time it takes to falla known distance is measured. Very precise results can be produced with this method ifsufficient care is taken in measuring the distance fallen and the elapsed time.
A 1.5-kg fireworks shell is fired at an angle of 19∘19∘ from the vertical from a mortar and reaches a height of 39 m39 m. Take the upward direction to be positive for this problem. a.) Neglecting air resistance (a poor assumption, but we will make it for this problem), calculate the the magnitude of the shell's initial velocity, in meters per second, when it leaves the mortar. b.) The mortar is a tube that has length L=0.425m. Calculate the average acceleration of the shell, in meters per second squared, in the tube as it is propelled from rest to the speed found in part (a). c.) What is the average net force, in newtons, acting on the shell in the mortar?
Dave with a mass of 60 kg goes tubing down a 20 m long hill that has an angle off the horizon of 25º. (Gravity applies) a. He gets a push from the bottom of the hill, so his initial velocity is 2 m/s. How far up the hill will he go before stopping? (there’s no friction) b. He goes back down the hill and then his friend Jill tries to pull him on the tube across a small patch of grass (μk=0.30). If she is pulling parallel to the ground at constant 5 m/s for 5 sec how much power does she expend? c. After climbing back uphill, Dave decided to roll down the hill instead. If he were to be a long cylinder with a radius of 0.1 m, what is his moment of inertia? d. After rolling without slipping down the hill, what is Dave’s final velocity at the bottom of the hill?

On Mars, a ball is rolling from a ground to a hill, and we know the height of the hill, Z, is 10 m, and the initial velocity ofthe ball on the ground and the final velocity on the hill are known: V1 = 20 m/s and V2 = 10 m/s, respectively. The mass ofthe ball, m, is 4 kg. The gravitational acceleration on Mars, gMars, is 3.7 m/s2. Please calculate 1) the change in kineticenergy, ΔKE, in J and 2) the change in potential energy, ΔPE, in J, of the ball for the rolling process.
