Step-by-step explanation:
Solution:
(a) is the vertical direction, the force of gravity
on the object (or the wight force: w = Mg ) pulls the crate down while the surface reaction. N. pushes it 103N
rd, as shown:
w = Mg = (20.0kg 9.8m s3 - 196N
N- 196N as well
(b) In the horizontal direction, in the absence of
friction, there are two forces: (F) and the 53-N force. Applying the Newton's 2nd law helps the calculation of the unknown force. F. F - 53N (20.0 kg)(2.5 m 3
F = 103N plz mark me as brainliest
Excuse me but I’m going to need to see the multiple choices?
Answer:
Step-by-step explanation:
Given that in a triangle ABC, AB = 28, BC = 24 and angle C =91,
We have to find measure of angle B.
Since three measurements are given, we can solve the triangle easily
Use the sine formula for triangles.


Since sum of 3 angles is 180, we calculate B easily
Angle B = 180-(A+C)
= 180-(91+58.98)
=30.02
