A model rocket launches with an initial velocity of 6 m/s, at an angle of 88 degrees (with respect to the horizon). The rocket's engine provides an acceleration of 2.2 m/s2, acting in the same direction as the initial velocity. After 23 seconds, the rocket engine cuts out. What is the maximum height attained by the rocket?
You may solve this problem using either tabulated values from the tables or constant specific heats. Calculate the rate of heat addition
drop a rock into a well. You hear the splash 2.40 s after you release the rock from rest. The speed of sound in air at the ambient temperature is 336 m/s. How far below the top of the well is the surface of the water?
An electron is accelerated by a uniform electric field (1000 V/m) pointing vertically upward. Use energy methods to get the magnitude and direction of its velocity

There is an 80 kg beam attached to a hinge on a wall and supported by the cord. The angle between the cord and the beam is 25 degrees. The beam is 4.5 m long., and cord is attached to the beam a metre from the beam's end. There is a 20 kg beam hangin..
Determine the value of the electric potential. calculate the acceleration of the ball when it is 3 cm from the surface and again at the position determined in part b.
A parallel-plate capacitor has plates of area 177.0 cm2 and a separation of 1.85 cm. Find the capacitance before the slab is inserted
The velocity of a boat with respect to the shore is 2 meters/second. The velocity of the water with respect to the shore is 1 meter/second. What is the distance traveled by boat after 3 minutes if the boat is traveling in the opposite direction of..
M1 is five times more massive than M2. One force acts on the hanging mass, but the net force acts on both masses. Once you have the acceleration, you can compute the distance.
