Answer:
<h3>25km/hr</h3>
Explanation:
Velocity is the change in displacement of a body with respect to time.
Velocity - Displacement/time
Given
displacement = 76km
Time = 3hours
Substitute the given parameters into the formula;
Velocity = 75km/3hrs
Velocity = 25km/hr
Hence the velocity of the narwhal is 25km/hr
Answer:
The object has 1250 Joules of Kinetic Energy.
Explanation:
Kinetic Energy =
mass*velocity²
KE =
mv²
KE =
(100kg)(5m/s)²
KE =
(100kg)(25m/s²)
KE = 1250
KE = 1250J
