Thanks for your help I don't know about it but could you tell me

but you forget to divide the Fy by Mass that -7.06/3 to get the ay that is -2.35 -------------------------------------------------------------------------------- a=((1.75^2) +(-2.35^2))^1/2 =2.93m/s^2

Ft=375 + 382 Ft=757N i that right

a=((1.75^2) +(-7.06^2))^1/2 =7.28m/s^2 how about it now

I think that Ft=375 + 382 Ft=757N But do you think the force (757N) can move the sleigh ( 2499N)?

Fx=ma 9cos0-8cos62=3a a=1.7m/^2 Fy=ma 9sin0-8sin62=ma ay= 1.97 a=(1.2^2 + 1.97^2)^1/2 a=2.30 m/s^2 is it right now and thanks for your help

A hors og mass 509 KG Pulls a sleigh of mass 255 KG and both horse and sleigh accelerate 0.5 m/s^2. the coefficient of friction for the sleigh is 0.150 as it moves over the snow. Find the horizontal force that the horse must exert on the sleigh. Remember sleighs have two identical blades on the...

Only two foces act on a 3.0 kg mass.? Only two foces act on a 3.0 kg mass. One of the forces is 9.0 N east, and the other is 8.0 N in the direction of 62.0 north of wet. What i the magnitude of the acceleration of the mass? The mass has only TWO forces acting on it. No gravity. Not resting on...

A satellite of mass 59.0 Kg is being pulled out of orbit by 450.0? 1- A satellite of mass 59.0 Kg is being pulled out of orbit by 450.0 Netwons of gravity. Small thrusters are used to maneuver the satellite back to its orbite. a)What thrust would cause the satellite to move with a constant...

I think this is ok now isn't it? F=4.8N F=ma 4.8kg*m/s^2=4kg*a a=1.2m/s^2 [u

Yes because the acceleration of the spring should be the same with the elevator. is the direction right that the acceleration is +1.2 m/s^2 that means that the elevator accelerates up?

I am really confused. 44-(4X9.8)= 4 X a a= 1.2 m/s^2 now I think that right because as you said the elevator has acceleration as the spring.

I think that was not right. because I am asked to find the elevator's acceleration. Mass of elevator is 44N / 9.8 = 4.5 44 N - (4.0 kg X 9.8) = a X 4.5 a = -1.1 m/s^2

If I said that N=w because the ball is not moving. still I could not solve it because I need to know more information which let me to be able to solve it because I have two unknewn variables that are W and N

I can understand that 44 N - (4.0 kg X 9.8) = a X4 a= 1.2 m/s^2 is it ok now
