Astuntman drives a car with a mass of 1500 kg on a drawbridge. the car accelerates with a constant force of 10,000 n. while he is driving, the drawbridge is raised to an incline of 30°. what is the car's new acceleration on this incline, ignoring the force due to air resistance? (recall that g=9.8 m/s^2)

1.77 m/s^2

Explanation:

There are two forces acting on the car along the direction parallel to the incline:

- The driving force of 10,000 N, which pushes forward

- The component of the weigth of the car parallel to the incline, which pulls backward

The component of the weight of the car parallel to the incline is:

So now we can apply Newton's second law to find the acceleration of the car:

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
