A bomber is flying horizontally over level terrain at a speedof 275 m/s relative to the ground and at an altitude of3.00 km. (a) The bombardier releases one bomb. How fardoes the bomb travel horizontally between its release and itsimpact on the ground? Ignore the effects of air resistance.(b) Firing from the people on the ground suddenly incapacitatesthe bombardier before he can call, “Bombs away!”Consequently, the pilot maintains the plane’s originalcourse, altitude, and speed through a storm of flak. Whereis the plane relative to the bomb’s point of impact when thebomb hits the ground? (c) The plane has a telescopic bombsightset so that the bomb hits the target seen in the sight atthe moment of release. At what angle from the vertical wasthe bombsight set?
In the standing broad jump, one squats and then pushesoff with the legs to see how far one can jump. Suppose theextension of the legs from the crouch position is 0.600 m andthe acceleration achieved from this position is 1.25 times theacceleration due to gravity, g . How far can they jump? Stateyour assumptions. (Increased range can be achieved byswinging the arms in the direction of the jump.)
A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.35 m/s at an angle of 71.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?

Coast Guard rescue swimmers are trained toleap from helicopters into the sea to save boaters in distress. Therescuers like to step off their helicopter when it is “ten and ten,”which means that it is ten feet above the water and moving forward horizontally at ten knots. What are (a) the speed and (b) thedirection of motion as a rescue swimmer enters the water following a ten and ten jump?
A student see's her physical professor approaching on the side walk that runs by her dorm , She gets a water ballon and waits. When the professor is 2.0s from being directly under the window about 11m from the sidewalk , she drops the balloon what happens?
The engineer of a passenger train traveling at25.0 m/s sights a freight train whose caboose is 200 m ahead on thesame track . The freight train is traveling at 15.0 m/s in thesame direction as the passenger train. The engineer of the passengertrain immediately applies the brakes, causing a constant accelerationof 0.100 m/s2 in a direction opposite to the train’s velocity, while thefreight train continues with constant speed. Take x = 0 at the locationof the front of the passenger train when the engineer applies the brakes.(a) Will the cows nearby witness a collision? (b) If so, where will it takeplace? (c) On a single graph, sketch the positions of the front of the passengertrain and the back of the freight train.
A pitcher throws horizontally a fast ball at 153 km/h toward the home plate, which is 18.1 m away. Neglecting airresistance (not a good idea if you are the batter), find how far the ball drops because of gravity by the time it reaches the home plate. Ans) _____m
A World War II bomber flies horizontally over level terrain with a speed of 275 m/s relative to the ground and at an altitude of 3.00 km The bombardier releases one bomb. (a) How far does the bomb travel horizontally between it release and its impact on the ground? Ignore the effects of air resistance. (b) The pilot maintains the planes original course, altitude, and speed through a storm of flak. Where is the plane when the bomb hits the ground? (c) The bomb hits the target seen in the telescopic bombsight at the moment of the bombs release. At what angle from tin- vertical was the bombsight set?
Give an example in which velocity is zero yet acceleration is not.
A hawk is flying horizontally at 10.0 m/s in a straight line, 200 m above the ground. A mouse it has been carrying struggles free its talons. The hawk continues on its path at the same speed for 2.00 s before attempting to retrieve its prey. To accomplish the retrieval, it drives in a straight line- at constant speed and recaptures the mouse 3.00 m above the ground. (a) Assuming no air resistance acts on the mouse, find the driving speed of the hawk. (b) What angle did the hank make with the horizontal during its descent? (c) For what time interval did the mouse experience free fall?
Is it possible for velocity to be constant while acceleration is not zero? Explain.
