Question

Megan rolls a ball down a ramp until the ball hits the wall. The ramp is 2.5m long and the distance from the end of the ramp to the wall is 1.5m. If it took 0.5 seconds for the ball to hit the wall then what is the ball's speed?

Answer 1

Answer:

$\text{ Speed of ball}=8 \frac{\text{ meters}}{\text{ second}}$

Step-by-step explanation:

To find speed of ball we will use $Speed=\frac{Distance}{Time}$ formula.

To find distance traveled by ball we will add length of ramp and distance from the end of ramp to the wall.

$2.5+1.5=4$

Now we will substitute our values in speed formula to find our answer.

$\text{ Speed of ball}=\frac{4\text{ meters}}{0.5\text{ seconds}}$

$\text{ Speed of ball}=\frac{40\text{ meters}}{5\text{ seconds}}$

$\text{ Speed of ball}=8 \frac{\text{ meters}}{\text{ second}}$

Therefore, speed of ball will be 8 meters per second.

Answer 2

The ball's speed if it took 0.5 seconds for the ball to hit the wall is 8m/s

The formula for calculating the speed of the ball is expressed as:

$Speed = Distance/Time$

If the ramp is 2.5m long and the distance from the end of the ramp to the wall is 1.5m, the total distance will be 2.5+1.5 = 4.0m

Given the following

Distance = 4.0m

Time = 0.5 seconds

Substitute the given values into the formula as shown:

$Speed =\frac{2.5+1.5}{0.5}\\ Speed = \frac{4.0}{0.5}\\Speed = 8m/s$

Hence the ball's speed if it took 0.5 seconds for the ball to hit the wall is 8m/s
