Answer:

78.26hp

Explanation:

q= 1700C

V=340V

t= 9.9s

1hp=746W

Energy obtained from the car= qv/t = 1700×340/9.9 × 1hp/746W= 78.26hp

Answer:

Explanation:

Given:

Time, t = 9.9 s

Charge, Q = 1700 C

Potential difference, V = 340 V

Power = IV

I × t = Q

Power = (1700 × 3400)/9.9

= 58383.8 W

= 58.38 kW.
