Jonah rode his skateboard 350 meters down a straight road at a constant velocity. He skated
1 answer:
Answer:
250 m/min down the road
Explanation:
Velocity is equivalent to speed but it considers the direction of the object. Velocity is also calculated by dividing the distance travelled by time. Therefore, where d and t are distance and time respectively. Given that d is given as 350 m and t is 1.4 s then by substitution
and the direction is down the road.
Velocity is 250 m/min down the road

Answer and Explanation:
Here's the answer!
Answer:
(A). The magnitude of the momentum of the marble is 0.004745 kg m/s.
(B). The speed of baseball is 23.0 m/s
Explanation:
Given that,
Mass of marble = 0.0073 kg
Speed = 0.65 m/s
(A). We need to calculate the magnitude of the momentum of the marble
Using formula of momentum
Where, m = mass
v = velocity
Put the value into the formula
(B). Mass of baseball = 0.136 kg
Momentum of baseball = 3.14 kg m/s
We need to calculate the speed of baseball
Using formula of momentum
Put the value into the formula
Hence, (A). The magnitude of the momentum of the marble is 0.004745 kg m/s.
(B). The speed of baseball is 23.0 m/s
