A team of dogs accelerates a \(200-\mathrm{kg}\) dogsled from 0 to \(5.0 \mathrm{~m} / \mathrm{s}\) in \(3.0 \mathrm{~s}\).

(a) What is the magnitude of the force exerted by the dogs on the sled? \((b)\) What is the work done by the dogs on the sled in the \(3.0 \mathrm{~s}\) ?

(c) What is the instantancous power of the dogs at the end of the \(3.0 \mathrm{~s}\) ?

(d) What is their instantaneous power at \(1.5 \mathrm{~s}\) ? Assume that the acceleration is constant.
