A Pepsi bottle is dropped (released) from a height of 60.0 m. How fast is it going (m/s) when it still has 2.0 s left in its fall?

An object is thrown straight up from ground level with a speed of 40 m/s. If g = 10 m/s2 its distance above ground level 2.0 second later is:

In the figure, a stone is projected at a cliff of height h with an initial speed of 43.0 m/s directed at an angle θ0 = 61.0 ° above the horizontal. The stone strikes at A, 5.18 s after launching. The height h of the cliff is

In the figure, a stone is projected at a cliff of height h with an initial speed of 36.0 m/s directed at an angle θ0 = 61.0 ° above the horizontal. The stone strikes at A, 5.18 s after launching. The height h of the cliff is

In the figure, a stone is projected at a cliff of height h with an initial speed of 39.0 m/s directed at an angle θ0 = 61.0 ° above the horizontal. The stone strikes at A, 5.18 s after launching. The height h of the cliff is

An electric vehicle starts from rest and accelerates at a rate of 1.5 m/s2 in a straight line until it reaches a speed of 27 m/s. The vehicle then slows at a constant rate of 3 m/s2 until it stops.  How far does the vehicle move from start to stop?

If the position of a particle is given by x = 30t – 3t3, where t is in seconds and x is in meters, when is the particle’s velocity zero?

In the figure below, elevator cabs A and B are connected by a short cable and can be pulled upward or lowered by the cable above cab A. Cab A has mass 1680 kg; cab B has mass 1500 kg. A 30 kg box of catnip lies on the floor of cab A. The tension in the cable connecting the cabs is 1.90 ×104 N. What is the magnitude of the normal force on the box from the floor?

In the figure, a crate of mass m = 30 kg is pushed at a constant speed up a frictionless ramp (θ = 40°) by a horizontal force F. The positive direction of an x axis is up the ramp, and the positive direction of a y axis is perpendicular to the ramp. The magnitude of F is.

Which of the following has the greatest chance of causing stomach irritation, and potentially causing bleeding?
