Answer:

i) 180m ii) 6sec ii)180m

Explanation:

i) Hmax = U²/2g

= 60²/20

= 3600/20= 180m

ii). Tmax= U/g

= 60/10= 6sec

iii). X= ut²+ 1/2gt²

since U is 0,then ut=0

X=0+ 1/2×10×6²

X=5×36= 180m

hope its clear??

A 5 cm spring is suspended with a mass of 1 g attached to it which extends the spring by 3.2 cm. The same spring is placed on a
notsponge [240]

First, we need to find the spring constant

Force of gravity = force of tension from spring

mg = kx

(1x10^-3)(9.8) = k (3.2x10^-2)

k = .30625

Now we can look at the other situation

Since the spring was moved 0.01 meters, we can find the force

F = kx = (.01)(.30625) = .0030625 N

Now we can set the electric force equal to the force of the beads

kq^2/r^2 = .0030625 N

q = 292 microCoulombs

Trained dolphins are capable of a vertical leap of 7.0m straight up from the surface of the water-an impressive feat.Suppose you
anzhelika [568]

Answer:

   θ = 45º

Explanation:

To find the solution, let's use the projectile launch equation

    R = vo² sin 2θ / g

Where vo is the initial speed of the dolphin, T is the angle of the jump and g the gravity acceleration.

To obtain a maximum range, the sine T function must be 1,

     sin 2θ = 1

     2θ = sin⁻¹ 1

     2θ = 90

     θ = 45º

Therefore, the dolphin should jump at an angle of 45º from the horizontal
