Tarzan (80 kg) jumps out of a tree at 1.4 m/s and grabs the end of a 32 m vine suspended suspiciously horizontal 36 m above the forest floor. What will be his speed at the bottom of his swing 4 m above the ground.? (Think pendulum)

object 2 because all the other ones are wrong

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
