change in velocity is 3m/s,the force exterted by bat on ball is 4.8N and the acceleration is 30m/s².
<h3>Give some difference between velocity and speed.</h3>
1) Speed is scalar quantity but velocity is vector quantity.
2) Speed is distance followed by an individual with respect to time and velocity is displacement with respect to time .
1) final velocity- intial velocity
25-22= 3m/s
2) The force is
F= ma
. 0.16×30= 4.8N

Answer:
<h2>
38,769.23 miles</h2>
Explanation:
given:
A car is traveling at an average speed of 70 m/s.
find:
How many km would the car travel in 6.5 hrs. ?
solution:
distance = velocity over time
let velocity = 70 m/s
time = 6.5 hrs.
convert velocity 70 m/s into m/h for consistency of units.
<u>70 mi. </u> x <u>3600 sec.</u> = 252,000 mi/hour
sec. 1 hr.
now plugin values into the formula d = v/t
d = <u>252,000 miles/hour </u>
6.5 hours
d = 38,769.23 miles
therefore, the distance travelled in 6.5 hours with a speed of 70 m/s is 38,769.23 miles
The answer would be C.30J
