A skateboarder is attempting to make a circular arc of radius r = 19m in a parking lot. The total mass of the skateboard and skateboarder is m = 81kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μ_s
A skateboarder is attempting to make a circular arc of radius r = 11 m in a parking lot. The total mass of the skateboard and skateboarder is m =78 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is
Following questions with the picture of the four different pulley systems. 1) What are the forces required to lift the weight up in each of the four pulley systems depicted in the picture? Please fill in the blanks with the corresponding forces.F1 – ( #1 ) N, F2 –
Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.2×106 N , one an angle 13 ∘ west of north and the other an angle 13 ∘ east of north, as they pull the tanker a distance 0.65 km toward the north. What is the total
Question: Newton’s 3rd law is often misquoted as “for every action there is an equal and opposite reaction”. What physics does Newton’s 3rd law describe and give an example that illustrates its meaning.
The sound level measured in a room by a person watching a movie on a home theater system varies from 55 dB during a quiet part to 75 dB during a loud part. Approximately how many times louder is the latter sound? I thought it was 100, but
A sandwich board advertising sign is constructed as shown in the figure below. The sign’s mass is 5.10 kg. (a)Calculate the tension in newtons in the chain assuming no friction between the legs and the sidewalk. N (b)What force is exerted in newtons by each side on the hinge? N
(part 1 of 2) A cheetah can run at a maximum speed 92.8 km/h and a gazelle can run at a maximum speed of 76.2 km/h. If both animals are running at full speed, with the gazelle 65.8 m ahead, how long before the cheetah catches its prey? Answer in
Consider the following three displacement vectors: Vector A has a magnitude of 3.80 km and a direction that makes an angle of 21.0° north of east, vector B has a magnitude of 7.00 km and a direction that makes an angle of 29.0° north of west, and vector C is
The Laws of Motion Worksheet Name: Instructions: For this assignment, describe Newton’s laws of motion while skateboarding. Next, study the graph of distance traveled to determine if the skateboarder is on a dry, wet, or muddy road condition. Describe how these conditions affect the motion of the skateboard. Then, complete
Given the equation in the image… for the vertical compression of a mirage near the horizon, evaluate this expression andcomment on what it means. You may assume the same values for R,h and n as in part (b).
A diagram of the human arm is shown holding a heavy iron ball (mass 5.0 kg). The triceps muscle connects to the forearm 3.0 cm to the left of the elbow joint, while the biceps muscle connects 5.0 cm to the right. Each of the muscles can exert an upward
