A roller coaster is pulled up a hill by a chain attached to a motor the total roller mass is 5000kg. If takes 20second to pull the roller coaster up 50 meter hill, how powerful is the motor? Power=work/time;=work=force*displacement
Added by Alcher G.
Step 1
To do this, we can use the equation: Force = mass × acceleration due to gravity Force = 5000 kg × 9.81 m/s² Force = 49050 N Show more…

a. How much work does an elevator motor do to lift a $1000 \mathrm{kg}$ clevator a hcight of $100 \mathrm{m} ?$ b. How much power must the motor supply to do this in 50 s at constant speed?
A roller coaster is towed up an incline at a steady speed of $0.50 \mathrm{m} / \mathrm{s}$ by a chain parallel to the surface of the incline. The slope is $3.0 \%,$ which means that the elevation increases by $3.0 \mathrm{m}$ for every $100.0 \mathrm{m}$ of horizontal distance. The mass of the roller coaster is $400.0 \mathrm{kg}$. Ignoring friction, what is the magnitude of the force exerted on the roller coaster by the chain?
A skier of mass $70 \mathrm{~kg}$ is pulled up a slope by a motordriven cable. (a) How much work is required to pull him $60 \mathrm{~m}$ up a $30^{\circ}$ slope (assumed frictionless) at a constant speed of $2.0 \mathrm{~m} / \mathrm{s}$ ? (b) What power must a motor have to perform this task?
