The acceleration due to gravity of an object on the Earth's surface
When the change in speed is in m/s and the time interval is in s, what is the unit of acceleration then?
"meters per second squared." The unit of time, the second, occurs twice- once for unit of speed and again for the time interval during which the speed changes.
For a scene in a movie, a stunt driver drives a 1.50×103kg SUV with a length of 4.25m around a circular curve with a radius of curvature of 0.333 km(Figure 1) . The vehicle is to be driven off the edge of a gully 10.0 m wide, and land on the other side 2.96 m below the initial side.
An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.250rev/s . The magnitude of the angular acceleration is 0.883rev/s2 . Both the the angular velocity and angular accleration are directed clockwise. The electric ceiling fan blades form a circle of diameter 0.800m .
Dario, a prep cook at an Italian restaurant, spins a salad spinner and observes that it rotates 20.0 times in 5.00 seconds and then stops spinning it. The salad spinner rotates 6.00 more times before it comes to rest. Assume that the spinner slows down with constant angular acceleration
If the create has a mass of 130kg and is 1.6 m tall and 0.80 m in depth and width, what is the minimum force needed to make the crate start tipping? (Assume the center of mass of the crate is at its center and static friction great enough to prevent slipping.)
