Puck 1 (1 kg) travels with velocity 30 m/s to the right when it collides with puck 2 (1 kg) which is initially at rest. After th

Katyanochek1 [597]

Answer:

v₂ = 22.5 m/s

Explanation:

Given that

For puck 1

m₁= 1 kg

u₁= 30 m/s

For puck 2

m₂= 1 kg

u₂= 0 m/s

After collision

Puck 1 have velocity v₁=7.5 m/s

Take puck 2 will have velocity v₂

From linear momentum conservation

P₁=P₂

m₁ u₁+m₂ u₂=m₁ v₁+m₂ v₂

1 x 30 + 1 x 0 = 1 x 7.5 + 1 x v₂

30 - 7.5 =v₂

v₂ = 22.5 m/s

Calculate the acceleration of a bus full speed changes from 6 miles to 12 miles over a period of three seconds

Jet001 [13]

Answer:

0.90m/s²

Explanation:

Given parameters:

Initial speed = 6miles/hr

Final speed = 12miles/hr

Time taken = 3 seconds

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time. It is mathematically given as:

Acceleration = $\frac{Final speed - Initial speed}{Time}$

We need to convert miles/hr to meters/seconds

Initial speed = 6 x $\frac{miles }{hour}$ x $\frac{1hr}{3600s}$ x $\frac{1609.34m}{1mile}$

= 2.68m/s

Final speed = 12 x $\frac{1609.34}{3600}$ = 5.37m/s

Acceleration = $\frac{5.37 - 2.68}{3}$ = 0.90m/s²

(a) the three resistors are in parallel, so the equivalent resistance R is given by

1/R= 1/5 + 1/10 +1/15

1/R= 11/30

R=2.7ohm

(b) Voltage in the circuit= 120 V

V= i R

120= i (2.7)

i=44 A
