Question

Given the equation (2.00 kg)(5.000 N 10.00 N, which answer or answers provide(s) the best description of a possible physical situation? (Select all that apply.) A 20.00 N force pushes a 2.00 kg mass. The 2.00 kg mass pushes another 2.00 kg mass. A 2.00 kg mass on a flat surface is acted on by gravity while another 2.00 kg mass sits on top of it. A 20.00 N tension pulls a 2.00 kg mass. The 2.00 kg mass pulls another 2.00 kg mass. Force and Motion Newton's Law Answer 75 points 13 PRE.003 My Not A block is given an initial velocity of 5.30 m/s up a frictionless 18.0° incline. How far up the incline does the block slide before coming to rest?

Explanation / Answer

Ans:-

# 20N force pushes a 2kg mass . the 2kg mass pushes another 2kg mass

FAB –FBA = MA*a

A and B boxes

# 20 N tension pulls a 2kg mass the 2kg mass pulls another 2kg

Applying Newton’s second law

T- Fg = mA*a

2. Given data vi = 5.30m/s, = 18

Apply Newton’s second law

F = m*a

mgsin 18 = m*a

-9.8*sin 18 = a = -3.03m/s^2

Now using equation of motion

V^2 = V0^2 +2as

0 = 5.30^2 +2*-3.03*s

S= 4.64m
