Answer:
141.56 N.
Explanation:
Data given:
Weight of the box= 200.2 N
Angle with the horizontal= 37.1°
Solution;
Gravitational force on the box, = weight of the box
= 200.2 N
Component of gravitational force along plane = ( ∅ )
= W * (sin∅)
= (200.1) * sin (37.1°)
= 141.56 N
Acceleration(a) is the change in velocity(Δv) over the change in time(Δt). so just divide your velocity and time.
