    Applying Newtons laws (intro to physics problem)

    A 20000 rocket has a rocket motor that generates 3.0×105 of thrust. What is the rocket's initial upward acceleration? Express your answer using two significant figures. At an altitude of 5.0 km the rocket's acceleration has increased to 6.0 m/s^2 . What mass of fuel has it burned...

    How large is the normal force? (applying Newtons laws phys )

    how large is the normal force? (applying Newtons laws phys 1111) A 23 kg child goes down a straight slide inclined 38 degrees above horizontal. The child is acted on by his weight, the normal force from the slide, kinetic friction, and a horizontal rope exerting a 30 N force as shown in the...

    Vectors and motion in 2D (physics problem)

    vectors and motion in 2D (physics 1111 problem!) The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans and animals. When grown in a uniform medium rich in salts and amino acids, these bacteria swim along zig-zag paths at a constant speed...
