A Physic student has a 0.25 m length of string. She attached one end to the ceiling and the other end to
a toy plane. If the toy plane weighs 0.5 kg, find the maximum speed of the plane and the angle that it
makes with the vertical if the maximum tension in the string before it snaps is 10 N.
A mass, m is hung as shown in Fig. Q2. Maximum tension in each cable AB and AC are

- On the way to Hilton Head, S.C. for Spring Break, your car breaks down in the middle of nowhere. A tow truck weighing 4500 lbs comes along and agrees to tow your car, which weighs 1800 lbs, to the nearest town. The driver of the truck attaches his cable to your car at an angle of 22° from the horizontal. He tells you that his cable has a strength of 550 lbs. He plans to take 10 seconds to tow your car at a constant acceleration from rest, in a straight line along the flat road, until he reaches the maximum speed limit of 45 miles/hour. Can the driver carry out his plan?
