A shot putter exerts a force of 100N acting forward and upward on a 40N shot put at an angle of 60° from horizontal. Other than gravity, the weight of the shot put (40N) is the only external force acting on it. a. What was the vertical component of this force? b. What is the horizontal component of this force? c. How big was the NET force (sum of all external forces) acting on the shot put? (remember gravity is...

An object with a mass of 5.69 kg undergoes an acceleration of -4.7 m/s^2 for a period of 5.8 seconds. It then undergoes an acceleration of 6.9 m/s^2 for a period of 8.7 seconds. If the initial velocity of the object is 1.51 m/s and it first experiences acceleration when it is at the origin, plot by hand a graph the force, velocity, and position as functions of time. Explain why your graph look the way they do and include...

1.) Luke Skywalker is running to fight Darth Vader, but slips on a patch of ice as he stops to draw his lightsaber (he’s on the planet Hoth). If he is running at 4 m/s, and decelerates at -2 m/s^2, then how far has he skidded on the patch of ice when he finally stops? and how long does that take? 2.) A shot putter releases the shot at 40° with respect to horizontal at a velocity of 13.3 m/s....
