The coefficient of kinetic friction between the 2.0 kg block in figure and the table is 0.310. What is the acceleration of the 2kg block? Someone please help me and show me at least the steps, I canno
The block of a mass 1.54869 kg has an acceleration of 2.6 m/s^2. There is a force pushing the block at an above of 27 degrees. What is the magnitude of the force? Assume acceleration due to gravity is
A rock is held steady over a cliff and dropped. 0.5 seconds later, another rock is thrown straight down at a speed of 9.9 m/s, and hits the first rock. How far have the rocks dropped before they colli
A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 21.0° below the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective
A brick is thrown upward from the top of a building at an angle of 35° to the horizontal and with an initial speed of 13 m/s. If the brick is in flight for 2.8 s, how tall is the building?

A duck has a mass of 3.0 kg. As the duck paddles, a force of 0.12 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.28 N in a direction of 47° south of ea
After falling from rest from a height of 35 m, a 0.52 kg ball rebounds upward, reaching a height of 25 m. If the contact between ball and ground lasted 2.5 ms, what average force was exerted on the ba
A ball rolls horizontally with a speed of 6.4m/soff the edge of a tall platform.

The height of a projectile at any time during flight is found from y(t) = h + Uyt - 1/2 gt^2; where h is the launch height at time t = 0, Uy is the vertical launch speed, and g is the gravity field.Th
While driving on the freeway at 110km/h , you pass a truck whose total length you estimate at 25m .

Cars can
Accelerate, Decelerate, and not move(when there parked)-The formula for speed is equal to distance/time (v=d/t).That is why speed is measured in k/hm (v=km/h).A car can travel x amounts of di
