Answer:
14.6 m/s
Explanation:
Momentum is conserved in the north:
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
After the collision, they stick together, so v₁ = v₂ = v.
m₁ u₁ + m₂ u₂ = (m₁ + m₂) v₂
(980 kg) (0 m/s) + (1500 kg) u = (980 kg + 1500 kg) vᵧ
1500 u = 2480 vᵧ
Momentum is conserved in the east:
m₁ u₁ + m₂ u₂ = (m₁ + m₂) v₂
(980 kg) (22.3 m/s) + (1500 kg) (0 m/s) = (980 kg + 1500 kg) vₓ
21854 = 2480 vₓ
vₓ = 8.81 m/s
The angle of v is 45.0°, so vᵧ = vₓ.
1500 u = 2480 (8.81 m/s)
u = 14.6 m/s
D = vt
where:
v = speed
d = distance
t = time
Based on the formula, each quantity is directionally proportional to each other. Since we don't have enough numbers to work with, we will utilize our concept skills.
If the car travels half the speed, then the car is slowing down and covers a short distance in a certain amount of time than it did originally. So we divide the default distance by 2.
180 / 2 = 90
The new distance so far is 90 miles.
But now it takes the car 3 times as long to get to its destination. The longer it takes, the more distance you will cover. Multiply the current distance by 3.
90 * 3 = 270
Answer:
A = [m/s]
B = [m/s²]
Explanation:
Assuming that V has SI units of m/s, then A and BT must also have units of m/s.
A = [m/s]
BT = [m/s]
Since T has SI units of s:
B [s] = [m/s]
B = [m/s²]
