Calculation the reaction forces at Ra and Rc taking upwards as postive S M +ve 8kN
For the beam below, let the uniform distributed load (w) be 15 kN/m and the beam spans length (L) be 5 m, and El=1000.0 kN/m . Taking redundant Rgt, use the force method to solve: w В + L L (1) 48 (m) for the primary beam; (2) 888 (m) for the primary beam with redundant Rg= 1 kN; (3) The vertical reaction Rg (kN); (4) The vertical reaction RA (kN); (5) The vertical reaction Rc (kN); < (6) The...
A ball is thrown vertically upwards with a speed of 20 m / s. (a) How fast is the ball when it is at a height of 15 m? (b) How long does it take you to reach that height?
A stone is thrown vertically upwards with a speed of 20.0 m / s. (a) What is its speed when it reaches 18 meters? (b) What maximum height does it reach?
an object propelled upwards with an acceleration of 2.0 m / s ^ 2 is launched from rest. After 6 seconds the fuel runs out. Determine the speed at this time and the maximum height at which it reaches.
A ball is thrown vertically upwards with a velocity of 29.5 m/s, from a window 84 m high. How long before the ball hits the ground?
Question 4 (1 point) You jump upwards off a diving board at 3 m/s. Where are you two seconds later? Question 4 options: 19.6 m below the diving board 13.6 m below the diving board 6 m above the diving board 19.6 m above the diving board 25.6 m above the diving board Question 5 (1 point) The Hermes spacecraft, taking astronauts from Earth to Mars, accelerates at 0.1 m/s^2 with an initial velocity of 30 km/s (the velocity of...
An object is thrown upwards with a speed of 10 m/s. How long does it take to reach a height of 2.0 m above the projection point while descending?
A ball is thrown vertically upwards at 29.4 m/s. For its complete trip (up and back down to the starting position), its average speed is: a. not given. b. 9.80 m/s. c. 14.7 m/s. d. 4.90 m/s.
A ball is thrown upwards with a speed of 19 m/s. it reaches a hight of 18.4 m above the point of release before it falls back down. Specify down as the positive direction and the initial position as the origin. If the balls position after three seconds is -12.9 meters, what is the distance traveled by the rock? The acceleration due to gravity is 9.8 m/s^2 down. The answer is 23.9 meters, how would i solve this?
6. A projectile is fired vertically upwards with initial speed 100 m/s. Find speed of the projectile in 15 seconds.
