This problem relates to a design competition in which a 1-kg battery-powered vehicle must be propelled up a 0.9-m tall ramp within a 15-second time interval. a. For a run time of 9 seconds, how much power must the battery supply to the vehicle

P = 0.98 W

Explanation:

Given that,

Mass, m = 1 kg

Height, h = 0.9 m

(a) We need to find power must the battery supply to the vehicle for a run time of 9 seconds. Power is given by work done divided by time. It can be given by :

So, the required power is 0.98 W.

dang that balls went far
