acceleration practice

A car has a speed of 15 m/s. Later de car has a speed of 23 m/s. This acceleration takes place in 13 seconds.

Calculate the acceleration.

Versnelling - Oefenvraag

A car has a speed of 15 m/s. Later de car has a speed of 23 m/s. This acceleration takes place in 13 seconds.

Calculate the acceleration

formule:

a=​Δt​​Δv​​

gegevens:

v(begin) = 15 m/s

v(end) = 23 m/s

t = 13 s

berekening:

∆v = 23 - 15 = 8 m/s

                                             

a=​Δt​​Δv​​=​13​​8​​=0,62

m/s2

resultaat:

a = 0.62 m/s2

Versnelling - Oefenvraag

A bicycle has an acceleration of 0.1 m/s2 for 12 s. Its final speed is 7.2 km/h. 

What is its speed after 5 seconds.

Versnelling - Oefenvraag

A bicycle has an acceleration of 0.1 m/s2. The initial speed of the cyclist is 7.2 km/h.

What is its speed after 5 seconds.

formule:

Δv=a⋅Δt

gegevens:

a = 0,1 m/s2

v(begin) = 7,2 km/h = 2 m/s

∆t = 12 s

berekening:

v(eind) = 2 + 1,2 = 3,2 m/s

v(eind) = 3,2 m/s = 11,52 km/h

resultaat:

v(eind) = 11,52 km/h

v(eind)=v(begin)+Δv

Δv=a⋅Δt=0,1⋅12=

1,2 m/s
