In the 1994 movie Speed, a bus wired with explosives must maintain a speed of 50mph or the bus will explode. In one of the movie's climactic scenes, the bus jumps a 50 ft. gap in the freeway. If the bus speeds up to 70mph before reaching the gap, what is the minimum launch angle required for the jump to be successful? Does the movie portray the physics adequately? You will probably need ti use the following trig identity: 2sin(theta)cos(theta)=sin2(theta).
