B3-CRT37: VELOCITY-TIME GRAPH-FORCE-TIME GRAPH Shown is the velocity versus time graph for an object that is moving in one dimension under the (perhaps intermittent) action of a single horizontal force. Velocity, m/s Time, s On the axes below, draw the horizontal force acting on this object as a function of time. Force Time Explain your reasoning.

An airplane starts from rest on the runway. The engines exert a constant force of 78.0 kN on the body of the plane (mass 9.20 × 104 kg) during takeoff. How far down the runway does the plane reach its takeoff speed of 64.6 m/s?

An object is pushed in x and y directions with the force vector F=-230i+10j (N). The object weighs 20kg and goes through a displacement of r=-2i-5j (m). What would be the final velocity of the object?

An airplane starts from rest on the runway. The engines exert a constant force of 78.0 kN on the body of the plane (mass 9.20 × 104 kg) during takeoff. How far down the runway does the plane reach its takeoff speed of 73.1 m/s?

An object has a mass of 15.3 kg and it has an initial velocity of 31.3 m/s (South) when it is acted upon by a force. The object's final velocity after the force has acted for a period of 5.20 s is 14.7 m/s (South). What is the force that acted on the object?

A bartender slides a mug of root beer with mass m - 2.4 kg down a bar top of length L 1.8 m to an inattentive patron who lets it fall a height h 1.4 m to the floor. The bar top (see figure below) is smooth but still has a coefficient of kinetic friction of HK 0.078. (Assume up and to the right as the positive directions.) (a) If the bartender gave the mug an initial velocity of 2.5 m/s, at what distance D from the bottom of the bar will the mug hit the floor? 0.9996 m (b) What is the mug's velocity (magnitude and direction) as it impacts the floor? Magnitude 75 Direction (counterclockwise from the +x-axis) 68.9 X m/s x ° (c) Draw velocity time diagrams for both the x and y directions for the mug, from the time when the bartender lets: go of the mug to when it hits the floor.
