Q1. Fuel aboard a rocket has a density of 2770 kg/m3 and is ejected with a speed of 3270 m/s. If the engine is to provide a thrust of 3.34 × 10^6 N, what volume of fuel should be burned per second?

Respond in units of m3/s

Q2. A baby bounces up and down in her crib. Her mass is 11 kg, and the crib mattress can be modelled as a light spring with force constant 654 N/m.

(a) The baby soon learns to bounce with utmost amplitude and minimum effort by bending her knees at what frequency?

(b) If she were to use the mattress as a trampoline-losing contact with it for part of each cycle-what minimum amplitude of oscillation does she require?

Q3. A charge moves a distance of 1.1 cm in the direction of a uniform electric field having a magnitude of 204 N/C. The electrical potential energy of the charge decreases by 59.6483 × 10-19 J as it moves.
