Determine the power required for a 1150-kg car to climb a 100-m-long uphill road with a slope of 308 (from horizontal) in 12 s (a) at a constant velocity, (b) from rest to a final velocity of 30 m/s, and (c) from 35 m/s to a final velocity of 5 m/s. disregard friction, air drag, and rolling resistance

Part a)

Power is defined as rate of work done

here we know that

so power is given as

Part b)

net work done on the block = change in kinetic energy

so power is given by

Part c)

Part b)

net work done on the block = change in kinetic energy

so power is given by

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
