We start with some review problems A crate of mass 34.7 kg rests on a level surface, with a coefficient of kinetic friction 0.127. You push on the crate with an applied force of 280 N. What is the magnitude of the crate s acceleration as it slides?     8.07 m/s^2     5.46 m/s^2     9.68 m/s^2     6.82 m/s^2

A rocket is descending to the surface of Mars where g = 4 m/s ^ 2 . The rocket is initially 80 m above the planet's surface and is descending downward at 50 m/s. The mass of the rocket is 2500 kg. The rocket will land on the surface with a final velocity of 0. Our goal is to find the upward thrust force on the rocket to make this happen. Draw a motion diagram .   Find the deceleration of the rocket. Draw force diagram for the rocket. Show the net force. Find the thrust force on the rocket ?

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

A block of mass 19.00 kg slides down an inclined surface at an angle 0 = 65.0° with speed v. The surface and block have a coefficient of kinetic friction my = 0.15. Determine the acceleration of the block down the inclined surface. 40.96 m/s^2 27.93 m/s^2 15.71 m/s^2 8.26 m/s^2

Blocks 1 and 2 are moving to the right on a frictionless surface by the tension TB = 36 N as shown. m1 = 2.0 kg, and m2 = 3.2 kg. What is the magnitude of the acceleration of block 2, in m/s²? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. m₁ TA m₂ TB
