Kurt s standing on a steel beam 275.0 ft above the ground and throws a hammer straight up at an initial speed of 40.0 ft/s. At the instant he releases the hammer, he also drops a wrench from his pocket Assume that neither the hammer nor the wench nits anything while in night (a) Fine the time difference between when the wrench and the hammer hit the ground (b) Find the speed at which the wrench hits the ground, (c) Find the speed at which the hammer hits the ground, (d) How long does it take for me hammer to reach its maximum height? (e) How high above me ground is the wench at me time the hammer reaches its maximum height?
