Question

a baseball is thrown a distance of 50 feet. what is its speed if it takes 2 seconds to cover the distance.

Answer 1

Answer:

Speed of a basket ball is 7.625 m/s is the answer.

Step-by-step explanation:

Total distance covered = 50 feet

1 feet = 0.305 metre

50 feet = 50 × 0.305 metres

50 feet = 15.25 metres

Time taken = 2 Seconds

$speed \: of \: basketball \: = \: \frac{total \: distance \: covered}{total \: time \: taken}$

Speed of basketball = 15.25/2 m/s

Speed of basketball = 7.625 m/s

Speed of basketball is 7.625 m/s

SPEED

• Total distance travelled in per unit time is called speed.
• It is a scaler quantity.
• Si unit of speed is m/s.
• Other units of speed are cm/s, km/hr etc.

Here,

m is metre.

cm is centimetre

km is kilometre

hr is hour.

Answer 2

Given ,

$\to$Distance = 50 feet = 15.25 m

$\to$Time = 2 sec

We know that ,

$\huge { \star} \: \: \large\fbox{ \fbox{ \sf Speed = \frac{Distance}{Time} }}$

$\implies \sf Speed = \frac{15.25}{2} \\ \\\sf \implies Speed = \frac{1525}{200} \\ \\ \sf \implies Speed = 7.625 \: \: m/s$

$\therefore$The required value of speed is 7.625 m/s
