An engineer is designing the runway for an airport. Of the planes that will use the airport,
the lowest acceleration rate is likely to be 5
m/s squared. Starting at 5 m/s, the plane will need to
take off in 11.4 seconds. How long is the
runway?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Your science teacher brings in a speaker to talk to your class about climate change. during the session, students ask a few questions. which questions are related to the current evidence on climate change

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
