Answer:
v₀ = 6.64 m / s
Explanation:
This is a projectile throwing exercise
x = v₀ₓ t
y = y₀ + v_{oy} t - ½ g t²
In this case they indicate that y₀ = 1.8 m and the point of the basket is x=4.9m y = 3.0 m
the time to reach the basket is
t = x / v₀ₓ
we substitute
y- y₀ =
y - y₀ = x tan θ -
we substitute the values
3 -1.8 = 3.0 tan 60 -
1.2 = 5.196 - 176.4 1 / v₀²
176.4 1 / v₀² = 3.996
v₀ =
v₀ = 6.64 m / s
Answer:
<h2>2.10 meters per second</h2><h2 />
Explanation:
speed (velocity) = distance / time
= <u>0.2 km (1000 m/km) </u>
95 secs.
= 2.10 meters per second
No I do not agree. It is because work is done when force acting o a body displace or covers certain displacement in the direction of force applied .
Yes it is, in other simplified terms density compares the amount of matter an object has to its volume.
