A car, initially traveling at 81.8 mi/h, slows to rest in 7.1 s. What is the car's acceleration?

maksim [4K]

Answer:

a = -16.9 ft/s²

Explanation:

81.8 mi/hr(5280 ft/mi / 3600s/hr) = 120 ft/s

a = Δv/t = (0 - 120) / 7.1 = -16.9 ft/s²

if the initial direction is taken as the positive direction.

A force vector has a magnitude of 599 newtons and points at an angle of 40.8° below the positive x axis. What is the x scalar co

ASHA 777 [7]

Answer:

$F_{x}=453.44N$

Explanation:

Given data

Force F=599 N

Angle α=40.8°

To find

x scalar component

Solution

The Scalar x component can be found by

$F_{x}=FCos\alpha \\F_{x}=599Cos(40.8)\\F_{x}=453.44N$

The Scalar y component can be found by

$F_{y}=-FSin\alpha \\F_{y}=-599Sin(40.8)\\F_{y}=-391.4N$
