Question

Spencal JCC to 10 • N9R.3 You are the physics consultant working on an action movie set where an SUV must start from rest, accelerate along a pier, and jump over a stretch of water to land in a departing ferry (the director assures you it will all be very exciting). The drawing below shows the situation. SUV, mass m 3 2D D Water Pier Ferry The SUV has four-wheel drive (see problem N5D.1), and the coefficients of friction between the tires and the pier's surface are pl. = 3/4 and = 1/2. Calculate the length L (as a fraction or multiple of D) of the run along the pier that vou will need for the SUV to make it to the ferry. (Ignore air drag.)

Answer 1
