Question

What is the speed of an object at rest?
a
1.0 m/s
b
9.81 m/s
c
0.0 m/s
d
9.8 m/s
Question 8 (1 point)
A dolphin swims 1.85 km/h. How far has the dolphin traveled after 0.60 h? d=v*t
a
0.63 km
b
3.7 km
c
2.5 km
d
1.1 km

Answer 1

For your first question about the speed of an object at rest, the correct answer is:

**c. 0.0 m/s**

An object that is at rest has a speed of zero.

For your second question regarding how far a dolphin swims, we can use the formula \( d = v \times t \).

Given:
- \( v = 1.85 \) km/h
- \( t = 0.60 \) h

Calculating the distance:

\[
d = 1.85 \, \text{km/h} \times 0.60 \, \text{h} = 1.11 \, \text{km}
\]

This would round to about 1.1 km, so the correct answer is:

**d. 1.1 km**
