In the standing broad jump, one squats and then pushes off with the legs to see how far one can jump. Suppose t = 0.55 m and the acceleration achieved during the time the jumper is extending their legs is 1.15 times the acceleration

A car is traveling horizontally at the moment it drives off the top of a 7.19 m tall cliff. The car travels 21.5 m horizontally before striking the ground. Assuming no air-resistance can be ignored, how fast was the car traveling at the moment it left the top of the cliff?

A grasshopper leaps into the air from the edge of a vertical cliff, as shown in Figure. It is given that the angle 0=52° and the distances d=0.11 m, and x=2.04 m. 不 d h : Ꮎ Not to scale X (a) Find the initial speed (in m/s) of the grasshopper. (b) Find the height h (in m) of the cliff.

As shown in the figure, a rock is shot upward from the edge of a vertical cliff. It leaves the edge of the cliff with an initial velocity of v directed at 30° from the horizontal direction and experiences no appreciable air resistance as it travels. The rock lands 2 seconds later. How high is the building?

A man throws a stone from the top of a building 164 m above the ground. Its initial velocity = 43.3( m)/(s) at an angle 30 degrees. As the stone hits the ground, find x.

At the end of the semester, you are loading your gear into a van to go home. In loading the van, you caneither lift a 45.0 kg crate straight up (method 1) or push it up a 3.00 m long ramp that is inclined at an angleθ above the horizontal line (method 2). In both methods, the crate is moved at a constant speed, and thevertical distance from the ground to the floor of the van has the same value h. In method 1, no friction ispresent. In method 2, however, a friction force does 485 J of work on the crate. In applying your non-conservative pushing force to the crate, you do twice as much work in method 2 as in method 1. Find theangle θ.     Determine the stability of a quad on a 20° slope in pull condition. The mass of the quad is 1,000 kg. Thedistance between the front and the rear axis is 400.0 cm, and the overall force of gravity for this quad islocated 150.0 cm from the rear axis and 100.0 cm from the ground (that is 100.0 cm perpendicular distancefrom the slope). The drawbar is…
