A crate slides down a frictionless ramp tilted at angle 30°. The acceleration direction parallel to the surface of the ramp is?

student throws a set of keys vertically upward to a friend, who is in a window 4m above. His friend catches the keys 1.5 s later. With what initial velocity were the keys thrown unit?

Which of the following situations is NOT possible?

What happens to an object when a non-zero net force is applied to it?

A plane landing with a speed of 360 km/h and decelerates at a rate of 6.00 m/s2 as it comes to rest. From the instant the plane touches the runway, what is the minimum time interval needed to rest?

An object, when pushed with a net force F, has an acceleration of 6 m/s2. Now eight times the force is applied to an object that has twice the mass. Its acceleration, in m/s2, will be:

🛑 In the figure, if the tension in string 1 is 34 N and the tension in string 2 is 24 N, what is the mass of the object shown in (kg)?

🛑 A block is pushed up a frictionless 30° incline by an applied force as shown. If F = 25 N and M =3.0 kg, what is the magnitude of the resulting acceleration of the block in (m/s2)?

A box is pushed with a force of 50 N to the right, and friction applies a force of 20 N to the left. What is the acceleration ( in m/s2)of a 10 kg box?

An object is moving with a constant velocity of 10 m/s. What can you conclude about the net force acting on it?

A student W 550N stands on spring scale in 950-kg elevator (including student). Elevator starts moving, scale reads the student's W as 517 N. The magnitude and direction of the elevator's acceleration
