A car is going along a circular road at a constant speed. The radius of the curve is 296 m, and the car takes 1.1 minutes to complete one round. Calculate its centripetal acceleration in m/s2.

Asample of a gaseous substance changes into liquid. this process is called (blank) and it takes place when heat is (blank) a gaseous system

1400 kg car has a speed of 27 m/s. if it takes 7 s to stop the car, what is the impulse and the average force acting on the car?
