Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Find the SI value of the constant A.
What impulse does the engine exert on the rocket during the 1.50 s interval starting 2.00 s after the engine is fired?
By how much does the rocket's velocity change during this interval? Assume constant mass.

At time t = 0 a 2250 kg rocket in outer space fires an engine that exerts an increasing
force on it in the +x-direction. This force obeys the equation F₂ = At², where t is time,
and has a magnitude of 781.25 N when t = 1.45 s.
