The 25 kg crate A as shown in Figure Q1 rest on the smooth incline plane. At initial position the spring is originally stretched 0.45 m. At the instant shown, the crate is applied with a horizontal force P = 800 N which leads to the motion at final position for a distance of 3 m. (a). Draw the free body diagram of all forces exerted on crate A. (b). Find the total work done by all forces acting on the crate A. (c). Determine the velocity and acceleration of the crate when it reached final position.

Question
Transcribed Image Text:The 25 kg crate A as shown in Figure Q1 rest on the smooth incline plane. At initial position the
spring is originally stretched 0.45 m. At the instant shown, the crate is applied with a horizontal force
P = 800 N which leads to the motion at final position for a distance of 3 m.
(a). Draw the free body diagram of all forces exerted on crate A.
(b). Find the total work done by all forces acting on the crate A.
(c). Determine the velocity and acceleration of the crate when it reached final position.
(d). Calculate the kinetic energy of crate A at final position.
