Could someone help me with these problems, because I have a test coming up and these are the suggested problems. Thank you
1) An airplane lands and starts down the runway at a southwest velocity of 45 m/s. What constant acceleration allows it to come to a stop in 1.4 km
2) Two blocks are connected by a lightweight, flexible cord that passes over a frictionless pulley. If m1 is 3.4 kg and m2 is 9.1 kg, and block 2 is initially at rest 140 cm above the floor, how long does it take block 2 to reach the floor?
