A car is parked on a cliff overlooking the sea. The cliff is inclined at an angle of 40.0 degrees below the horizontal. The negligent driver leaves the car in neutral and it begins rolling from rest towards the cliff's edge with an acceleration 5.00
m/s/s. The car moves a linear distance of 70.0 to the edge of the cliff before plunging into the ocean below. The cliff is
50.0 m above the sea. Round everything to 3 significant digits! Use 9.80 for gravity. (hint - because the initial velocity is
down, this causes the cosine rule to flip. Use sin to find Vox. Use cosine to find Viy)

Apassenger walks toward the rear of a moving train. describe her motion as seen from a reference point on the train. then describe it from a reference point on the ground

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
