Two blocks are connected by a light string that passesover a frictionless pulley as in Figure P5.38. The system is released from rest while m 2 is on thefloor and m1 is a distance h above thefloor. (a) Assuming m 1 >m 2, find anexpression for the speed of m1 justas it reaches the floor. (b) Takingm 1 = 6.5 kg, m 2 = 4.2 kg, andh = 3.2 m, evaluate your answer topart (a), and (c) find the speed ofeach block when m 1 has fallen a distanceof 1.6 m.
A man (mass 45 kg) shoots himself out of a cannon straight upward with an initial velocity of 46 m/s towards a ledge 95 m above the cannon. There’s some air resistance occurring, and the man’s upward trajectory ends 6.0 meters below the ledge. A) What was the average force of frictional air resistance the man experienced during his upward motion? B) Assuming the same average air resistance on the way down, how fast will the man’s impact velocity be when he returns to the “ground” level of the cannon’s muzzle? Please answer the question on paper. I do not understand when it is typed out. Thank you
The thrust created by a lone jet engine produces a force of F = 78000 N. It takes the aircraft (with a mass of m = 7300 kg) a distance of d = 0.71 km to take off. a.) What is the take-off speed of the aircraft vt in m/s? b.) How far in meters would you need to depress a giant spring k = 100,000 N/m in order to launch the aircraft at the same speed without help from the engine?

A projectile of mass 0.719 kg is shot straight up with an initial speed of 22.1 m/s. (a) How high would it go if there were no air resistance? (b) If the projectile rises to a maximum height of only 8.70 m, determine the magnitude of the average force due to air resistance.
An Atwood’s machine is set up by suspending two blocks connected by a string of negligible mass over a pulley, as shown above. The blocks are initially held at rest and then released at time t0=0 s.
