A ship sets sail Cape Ann, Massachusetts, heading due north at 7.00 m/s relative to the water. The local ocean current is 1.50 m/s in a direction 40.0o north of east. What is the velocity of the ship relative to the Earth

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

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?
