A car starting from rest accelerates uniformly are attaing a speed of 80m/s in 30s it maintains this stedy speed for another 30s. It then slow down uniformly until it comes to rest in the next 40s

Two workers are trying to move a heavy crate. One pushes on the crate with a force A, which has a magnitude of 445 N and is directed due west. The other pushes with a force B, which has a magnitude 325 N and is directed due north. What is the direction that the workers push ...

when a horizontal force of 300N is applied to 75kg crate, it slides on a level floor opposed by a force of friction equal to 95N. what is the acceleration of the crate?

Physics
Work in SI units. 92 mph = 41.12768 meters / second mgh= 1/2 m (41.13^2) h= 1/(2g) * 41.13^2) g= 9.8m/s^2

An crate weighing 576 N is resting on a plane inclined 29 above the horizontal. The magnitude of the acceleration (ignore friction) is1 m/s2. After 5.00 s, how fast will the crate be moving?

Precalculus Someone please help
draw the triangle, but first, scale it (that wont change the angle). (40,-9) works. That makes the hypotenuse sqrt(40^2+9^2)-=41 so you have a triangle, in the fourth quadrant sides 40, -9, with a hypotenuse of 41 sin= -9/41 cos= 40/41 You take it from here.

Physics
A crate is given an initial speed of 3.1 m/s up the 29 degree plane shown in the figure . Assume coefficient of friction = 0.17. How far up the plane will it go? How much time elapses before it returns to its starting point?

quadratic equations
6^2-8+41 =36-8+41 =28+41 =69 If it is a quadratic equation, the unknown (usually x) is missing, and something should appear on the right hand side.
