A child's 200gm toy car is driven by an electric motor that has a constant output power. The car climb a `20^(@)` incline at `20cm//s` and can travel on a horizontal table at `40 cm//s` The friction force retarding it is kv, where k is a constant and v is its speed. How steep in incline can it climb with a speed of `30 cm//s` ?
