Jim Master attempts to lift a 100 kg barbell, but his strength fails. If the net force is 400N, identify the dominant force the magnitude and direction of the acceleration.
A)
Tension, 4 m/s/s upward
B)
Tension, 9.8 m/s/s upward
C)
Gravity, 4 m/s/s/ downward
nare
D)
Gravity. 9.8 m/s/s downward

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)

14. a body is projected with velocity vi from a.at the same time another body is projectedvertically upwards from point b withvelocity v2 lies vertically below the highestpoint. both the bodies collide thenv2÷v1is

This is the number of complete movements of a wave per second.
