Homework Answers
(a)
From the Newton second law of motion , the net force acting on the body is
F = ma = 1.0 kg ( 9.64 m/s^2) = 9.64 N
x component of force
Fx = F cos theta = 9.64 N cos 58 = 5.10 N
(b)
y component is
Fy = F sin theta = 9.64 N sin 58 = 8.17 N
(c)
F = 5.10 N i + 8.17 N j
magnitude
F = sqrt ( 5.10)^2 + (8.17)^2 = 9.64 N
Add Answer to:
If a 1.00 kg body has an acceleration of 9.64 m/s^2 at 58 degree to the...

Tarzan, who weighs 838 N, swings from a cliff at the end of a 24.9 m vine that hangs from a high tree limb and initially makes an angle of 21.5° with the vertical. Assume that an x axis points horizontally away from the cliff edge and a y axis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is 780 N. Just then, what are (a) the force from the vine on Tarzan in...

A 23 kg body is moving through space in the positive direction of an x axis with a speed of 340 m/s when, due to an internal explosion, it breaks into three parts. One part, with a mass of 4.9 kg, moves away from the point of explosion with a speed of 51 m/s in the positive y direction. A second part, with a mass of 5.4 kg, moves in the negative x direction with a speed...
