- < Question 9 of 20 Bob has just finished climbing a sheer cliff above a beach and wants to figure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the ground with a long measuring tape. Bob is a pitcher, and knows that the fastest he can throw the ball is to = 91.0 mph. Bob starts the stopwatch as he throws the ball (with no way to measure the ball's initial trajectory) and watches carefully. The ball rises and then falls, and after f₁ = 0.910 s, the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball landed a distance of x = 332 ft from the base of the cliff. How high up is Bob if the ball started from exactly 5 ft above the edge of the cliff? height of the cliff: 5 fi TOOLS x10Problem 1 - Unit Conversions A plane moves with speed v = 400 km/h; rewrite v in m/s. The density of iron is approximately p = 7.8 g/cm; what is the density of iron in kg/m? Problem 2 - Velocity and Acceleration A point particle moves along the r axis, and its position as a function time is given by the equation z(t) = At² – B ,Before an experiment, you calculated the range of a projectile to be 2.55m. When you performed the experiment, you measured the range of the projectile to be 2.39m. What is the percent error for the range of the projectile?
