Answer: a= 2 m/s²
Explanation: acceleration = change of speed/ time = 20 m/s / 10 s
Answer:
10.21m/s²
Explanation:
Radial acceleration, also known as centripetal acceleration, refers to the acceleration of an object along the circular radius. It can be calculated using the formula:
a(r) = v²/r
Where a(r) = radial acceleration
v = velocity
r = radius of the circular path
According to the information provided in the question, velocity (v) = 17.5m/s, radius = 30m. Hence;
a(r) = v²/r
a(r) = 17.5²/30
a(r) = 10.208333
a(r) = 10.21m/s²
Work = (force) x (distance)
Work = (22 N) x (16 m)
<em>Work = 352 Joules</em>
