Question

a block is pulled 0.90m to the right in 2.4s what is the blocks average speed to the nearest hundredths of m/s

Answer 1

Answer:

$0.38\:\mathrm{m/s}$

Step-by-step explanation:

Average velocity is given by $v=\frac{\Delta x}{\Delta t}$, where $\Delta x$ is displacement and $\Delta t$ is change in time.

What we know:

• $\Delta x$ is $0.90\:\mathrm{m}$
• $\Delta t$ is $2.4\:\mathrm{s}$

Solving for $v$:

$v=\frac{0.90}{2.4}=0.375\approx\boxed{0.38\:\mathrm{m/s}}$
