Assuming 95 0 efficiency for the conversion of electrical power by the motor, what current must the 12 0 V batteries of a 750 kg electric car be able to supply (a) To accelerate from rest to 25 0 m s in 1 00 min (b) To climb a 2 00 x 10 2 m high hill in 2 00 min at a constant 25 0 m s speed while exerting 5 00 x 10 2 N of force to overcome air resistance and friction (c) To travel at a constant 25 0 m s speed, exerting a 5 00 x 10 2 N force to overcome air resistance friction See Figure 20 40 e NV200

Question: Assuming 95.0% efficiency for the conversion of electrical power by the motor, what current must the 12.0-V batteries of a 750-kg electric car be able

Assuming 95.0% efficiency for the conversion of electrical power by the motor, what current must the 12.0-V batteries of a 750-kg electric car be able to supply:

(a) To accelerate from rest to 25.0 m/s in 1.00 min?

(b) To climb a 2.00 x 10²-m-high hill in 2.00 min at a constant 25.0-m/s speed while exerting 5.00 x 10² N of force to overcome air resistance and friction?

(c) To travel at a constant 25.0-m/s speed, exerting a 5.00 x 10² N force to overcome air resistance friction? See Figure 20.40.
