Answer:
The answer is 5.86m/s
Explanation:
Acceleration is defined as the change in velocity of a body with respect to time. Mathematically,
Acceleration = change in velocity/time(t)
Change in velocity = final velocity (v)- initial velocity (u)
Acceleration = v-u/t
Given the following;
Acceleration = 0.75m/s²
Initial velocity = 3.35m/s
Time taken = 3.35s
Final velocity = v
Substituting the data given in the formula to get the final velocity we have;
0.75 = (v-3.35)/3.35
0.75×3.35 = v-3.35
2.51 = v-3.35
v = 2.51+3.35
v = 5.86m/s
Therefore the new velocity of the object will be 5.86m/s
Given Information:
Acceleration = a = 0.750 m/s²
Initial velocity = v₁ = 3.35 m/s
time = t = 3.35 seconds
Required Information:
new velocity = v₂ = ?
Answer:
new velocity = 5.86 m/s
Explanation:
We know from the kinematic equations,
v = u + at
Here u = v₁ and v = v₂
v₂ = v₁ + at
v₂ = 3.35 + 0.750*3.35
v₂ = 3.35 + 2.512
v₂ = 5.86 m/s
Therefore, the new velocity of the boat after it was accelerated by a river current is 5.86 m/s.
