Calculate the acceleration of a 2-kg block on a horizontal tuition-free air table when you exert a horizontal net force of 20 N. What acceleration occurs if the friction force is 4 N?

Find the work done by a force F= 2i (magnitude 2 N) in moving an object along the line from the origin to the point (5,5) (distance in meters). ..... The work done is J.

A 2 kg block is on a table with a coefficient of kinetic friction of 0.3.  How much applied force would you need to accelerate it from rest to 5 m/s in 0.5 seconds?

To maintain a constant speed, the force provided by a car's engine must equal the drag force plus the force of friction of the road (the rolling resistance). The density of air is 1.2 kg/m³. (a) What are the drag forces in newtons at 75 km/h and 109 km/h for a Toyota Camry? (Drag area = 0.70 m² and drag coefficient = 0.28.) at 75 km/h at 109 km/h N N (b) What are the drag forces in newtons at 75 km/h and at 109 km/h for a Hummer H2? (Drag area = 2.44 m² and drag coefficient = 0.57.) at 75 km/h at 109 km/h N N
