An object with a mass, m = 5 kg, is released from rest at the top of the ramp. The length of the ramp is 2.3 m. The object slides down the ramp reaching a speed of 2.1 m/s at the bottom. a) If the friction force between the ramp and the object is 3 N, find the angle between the ramp and the horizontal theta (in degrees). b) What speed (in m/s) does the object reach at the bottom...
An object of mass 0.61 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 14.8 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval.
An object of mass 0.53 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 14.1 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval. N
An object of mass 8.00 kg starts from rest and a slides 2.00 m down a rough 35.0° incline. The coefficient of kinetic friction between the block and the incline is 0.366. Determine (b) the work done by the friction force between block and incline (This part (b) of the previous question) 0 -47.00 0 -23.5) 0 -38.6) O-46.3)
Assume an object with mass m = 4.64 kg starts at rest at the origin and experiences a net force Fnet of (2.74t? į + -7.65j) N. What is the y-component of this object's velocity vector at time t = 3.59 s?
A package of mass m = 2.00 kg is released from rest at the top of an inclined plane as seen in the figure. The package starts out at heighth = 0.200 m above the top of the table, the table height is H = 2.00 m, and 0 = 50.0° R- (a) What is the acceleration (in m/s) of the package while it slides down the incline? 7.50 m/s² (b) What is the speed (in m/s) of the package...
An object of mass 4.00 kg is sitting at the top of an inclined plane of height h and angle θ with the horizontal. The object slides down the inclined plane and right before it reaches the bottom of the plane, it has speed of 16.0 m/s. Neglect friction. What is the height of the inclined plane?
did I do it right? An object with a mass of 10 kg is at rest at the top of a frictionless inclined plane of height 8.00 m and an angle of inclination 30.0 degree with the horizontal. The object is released from this position and it stops at a distance d from the bottom of the inclined plane along a horizontal surface, as shown in Figure 8-9. The coefficient of kinetic friction for the horizontal surface is 0.400 ad...
