Answer:
<em>Their displacement is 5 Km from the cabin.</em>
Explanation:
The displacement is define is the shortest distance between two points. It is the shortest distance of a line that joins two points together. It quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory. In this case, the straight line joining the cabin to the stream is line S which is equal to 5 Km
Answer:
Explanation:
The distance of searchlight will act as radius R and velocity of car may be supposed to be tangential velocity v . We are required to calculate angular velocity ω .
v = 80 ft /s
R = 3000 ft
ω = v / R
= 80 / 3000 = .027 rad / s
For angular acceleration the formula is
angular acceleration α = a / R
a is linear acceleration = 15 ft / s²
α = 15 / 3000 = .005 rad / s².
Answer:
1.31Kgms-1
Explanation:
∆p = m∆v
Where:
∆p= change in momentum
m= mass of the ball
∆v= change in velocity of the ball= (5.3-2.4)= 2.9ms-1
Therefore, substituting appropriately with the values above:
∆p= 0.45×2.9= 1.31Kgms-1
