#4 is correct.
For #5, don't get all tangled up. Just close your eyes, breathe deeply, and murmur "F equals M A. Force equals mass times acceleration."
The force is 15N. The mass is 12kg. You really shouldn't have any trouble calculating the acceleration.
Answer:
Vrel_jon's = 15 [m/s] to the right
Explanation:
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion.
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion. The relative velocity is defined as the algebraic sum of the velocities, if the movements are opposite the vectors are subtracted, as will be done below.
Vrel = 20 - 5 = 15 [m/s]
A person watching Jon sees him moving to the right at a speed of 15 [m/s]
First the total distance is 30+60+25+40 so 155m travelled and for c the displacement can be found By Final position - instal position
Answer:
the student is modeling a convergent plate boundary. The image shows the plates colliding to form a mountain-like structure
Explanation:
My cousin took the exam
F=ma
a=(v2-v1)/(t2-t1)
a=(6-0)/(12-0)
a=6/12
a= .5 m/s^2
f=2300kg*.5m/s^2
f=1150N
f=1200N if using correct sig figs
