The Laws of Motion
A force F applied to an object of mass 𝑚1 produces an acceleration of 3.00 m/𝑠 2 . The same
. force applied to a second object of mass 𝑚2 produces an acceleration of 1.00 m/𝑠 2 ?What is the value of the ra9o 𝑚1 /𝑚2 (a)
.If 𝑚1 and 𝑚2 are combined, find their acceleration under the ac9on of the force F (b)
. A 3.00-kg object undergoes an acceleration given by a = (2.00𝒊+̂ 5.00𝒋)̂ m/𝑠 2 .Find the resultant force acting on it and the magnitude of the resultant force
A 3.00 kg crate slides down a ramp. The ramp is 1.00 m in length and inclined at an angle of 30.00 , as shown in Figure. The crate starts from rest at the top, experiences a constant friction force of magnitude 5.00N, and continues to move a short distance on the horizontal .floor after it leaves the ramp
Find the acceleration of the crate and determine the speed of the crate at the bottom of the .ramp
A 5.00-kg object placed on a frictionless, horizontal table is connected to a string that passes over a pulley and then is fastened to a hanging 9.00-kg object, as in Figure. Draw free-body diagrams of both objects. Find the acceleration of the two objects and the tension in the .string
Two objects are connected by a light string that passes over a frictionless pulley, as in Figure.
Draw free-body diagrams of both objects. If the incline is rough ( 𝜇𝑘 = 0.2) and if 𝑚1 = 2.00
kg, 𝑚2=6.00 kg, and 𝜃 =55.0°, find (a) The accelerations of the objects, (b) The tension in the .string, and (c) The speed of each object 2.00 s after being released from rest
