008 (part 1 of 3) 10.0 points a 3.2 kg object is subjected to two forces, f~ 1 = (1.9 n) ˆı + (−1.9 n) ˆ and f~ 2 = (3.8 n) ˆı + (−10.1 n) ˆ. the object is at rest at the origin at time t = 0. what is the magnitude of the object’s acceleration? answer in units of m/s 2 .

What properties of a moving object are used in determining the object's energy of motion

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
