An arrow is shot at a target 20 m away. The arrow is shot with a horizontal velocity of 80 m/s.

Verdich [7]

(1) The time of motion of the arrow is 0.25 s.

(2) The vertical height dropped by the arrow as it approaches the target is 0.31 m.

The given parameters:

Horizontal distance of the arrow, X = 20 m
Horizontal speed of the arrow, v = 80 m/s

The time of motion of the arrow is calculated as follows;

$t = \frac{X}{v} \\\\t = \frac{20 }{80} \\\\t = 0.25 \ s$

The vertical height dropped by the arrow as it approaches the target is calculated as follows;

$h = v_0_y t + \frac{1}{2} gt^2\\\\h = 0 \ + \ \frac{1}{2} \times 9.8 \times 0.25^2\\\\h =0.31 \ m$

An object with a mass of 5.0 kg accelerates 8.0 m/s² when an uknown force is applied to it. what is the amount of the force?

Harman [31]

Mass=5kg
Acceleration=8m/s^2

Using newtons second law

$\\ \sf\longmapsto Force=Mass\times Acceleration$

$\\ \sf\longmapsto Force=5(8)$

$\\ \sf\longmapsto Force=40N$
