The acceleration of the car is $8.9 m/s^2$

Explanation:

The acceleration of an object is given by

$a=\frac{v-u}{t}$

where

v is the final velocity

u is the initial velocity

t is the time elapsed

Here we have to convert the initial and final velocity of the vehicle into SI units. So we have:

$u = 0$ is the initial velocity

$v=100 mph \cdot \frac{1609 m/mi}{3600 s/h}=44.7 m/s$ is the final velocity

t = 5 s is the time elapsed

Solving for a, we find the acceleration:

$a=\frac{44.7-0}{5}=8.9 m/s^2$

when a metal sphere is dropped in to a tall cylinder containing liquid its acceleration is g÷2 (gravity over 2) show that : dens

Mamont248 [21]

The density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.

<h3>What is the relationship between acceleration and density?</h3>

For a solid falling through a viscous fluid, the acceleration of the object decreases until it attains terminal velocity.

The acceleration of the body increases with increase in density of the solid.

When density of solid = density of liquid, acceleration a = g

When density of solid = 2 × density of the liquid, acceleration a = g/2.

Therefore, the density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.

A dart is thrown horizontally at a target's center that is 5.00 m, away. The dart hits the target 0.150 m below the targets cent

boyakko [2]

Answer:

v₀ₓ = 28.6 m / s

Explanation:

This is a missile throwing exercise

y = $v_{oy}$ t - ½ g t²

as the dart is thrown horizontally the vertical velocity is zero (I go = 0)

y = - ½ g t²

t = $\sqrt{- \frac{2y}{g} }$

let's calculate

t = $\sqrt{- \frac{2 \ (-0.150)}{9.8} }$

t = 0.175 s

the expression for horizontal displacement is

x = v₀ₓ t

v₀ₓ = x / t

v₀ₓ = 5.00 / 0.175

v₀ₓ = 28.6 m / s
