Children are playing with a remote-controlled toy jeep in an open horizontal field. At some time, the jeep is located (relative to a rock which they are using as the origin) at r→0 = (14.0i^ − 7.50j^) m and has a velocity of v→0 = (8.00i^ + 3.00j^) m/s. If, for a time interval Δt = 10.0 s, the jeep experiences a constant acceleration a→ and acquires a new velocity v→ = (2.00i^ − 19.50j^) m/s, determine the following for the jeep. (Express your answer in vector form.) (a) position vector at time t = 10.0 s r→(t = 10.0 s) = m (b) velocity vector time t = 5.00 s v→(t = 5.00 s) = m/s
