here,
the total impulse delivered , I = 23 N.s
the mass of rocket , m = 0.156 kg
let the speed of rocket after it is launched from rest be v
impulse = m * v
23 = 0.156 * v
solving for v
v = 147.4 m/s
the speed of rocket after it is launched from rest is 147.4 m/s

1) A 48.5-kg skater is standing at rest in front of a wall. By
pushing against the wall she propels herself backward with a
velocity of -1.46 m/s. Her hands are in contact with the wall for
1.00 s. Ignore friction and wind resistance. Find the average force
she exerts on the wall (which has the same magnitude, but opposite
direction, as the force that the wall applies to her). Note that
this force has direction, which you should indicate...

A 1000 kg weather rocket is launched straight up.The rocket motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 6200 m. You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16s? What is the rocket's speed as it passes through acloud 6200 m above the ground?

A rocket is launched from the Earth’s surface. Unfortunately, the engineers have miscalculated and the rocket runs out of fuel when its height is exactly one earth radii above the earth’s surface. The rocket immediately falls from rest back to toward the surface. Ignore friction and air resistance in your calculations.

3.43 CP A test rocket Figure P3.43 starting from rest at point A is launched by accelerating it along a 200.0-m incline at 1.48 m/s (Fig. P3.43). The incline rises at 35.0° above the horizontal, and at the in- stant the rocket leaves it, the engines turn off and the rocket is subject to gravity only (ignore air resistance). Find (a) the maximum height above the ground that the rocket reaches, and (b) the rocket's greatest horizontal range beyond point...

Q9: A test rocket is launched from rest over a ramp of 100 m that is inclined by an angle of 30 degrees from the horizontal. Along the ramp, the rocket is accelerated by a force of F(x)=4x N. At the instant the rocket leaves the ramp, the force F(x) drops to zero, and the rocket is now subjected only to gravity (free fall). *New information: mass of rocket m= 1kg. a) Calculate the magnitude of the velocity of the...
