A ramp 15 ft long rises to a platform that is 13 ft off the ground. Find x, the angle of elevation of the ramp. Round your answer to the nearest tenth of a degree. Platform x = 0 Ground
A 7.4kg block starts 1.2m above the ground, at the top of a frictionless ramp. At the bottom of the ramp is a flat stretch of rough (ulk = 0.15) ground 3.0m long. After sliding 3.0m, the ground becomes frictionless, and the block hits a spring (k = 1.6kN/m). a. Calculate the speed of the block at the bottom of the ramp. m b. Calculate the speed of the block just before it hits the spring. c. Calculate how far...
According to the Americans with Disabilities Act, a ramp cannot
have an incline that is greater than 5o. The regulations
also state that the maximum rise of a ramp is 30 inches. When a
ramp needs to reach a height greater than 30 inches, a series of
ramps connected by 60-inch landings can be used, as shown
below.
a) What is the maximum horizontal length of the base of one
ramp, in feet? Round to the nearest foot
length =...
A stunt car enters a ramp with an incline of 30 degrees, the car has an initial velocity of 40 m/s, and accelerates along the entire length of the ramp at 5 m/s^2. The ramp is 200 m long, and the height of the ramp is 100 m. However the ramp is then placed on a surface which is 90m up from the ground. The cars velocity as it reaches the end of the ramp is 60 m/s, and it...

A man 6.50 ft tall approaches a street light 17.0 ft above the ground at the rate of 5.00 ft/s. How fast is the end of the man's shadow moving when he is 8.0 ft from the base of the light? 17.0 ft 6.50 ft 5.00 ft/s The end of the man's shadow is moving at a rate of ft/s (Round to two decimal places as needed.)
An object is dropped from a tower, 1024 ft above the ground. The object's height above ground i seconds after the fall is s(t) = 1024 - 1612. Determine the velocity and acceleration of the object the moment it reaches the ground. ft/s. The velocity of the object the moment it reaches the ground is (Simplify your answer.) The acceleration of the object the moment it reaches the ground is fus2 (Simplify your answer.)
1 A ball is dropped from 20.0 ft above the ground. Using energy considerations only, what is the velocity (in ft/s) of the ball just as it hits the ground? Enter answer 2 What is the velocity (in m/s) of a 55.0 kg jogger with a kinetic energy of 1,380.0 J? Enter answer 3. A small sports car and a pickup truck start coasting down a 35.0 m hill together, side by side Assuming no friction, what is the velocity...
