Question

Brian's friend Jasmine has a skateboard that she likes to ride home from school. If the combined mass of Jasmine and the skateboard is 60 kg, and the net force acting at the height of her jump (see picture below) is 30 N, what is the acceleration at the height of the jump?

Answer 1

a = 0.5 m/s²

Step-by-step explanation:

Given data:

Mass of skateboard and jasmine = 60 Kg

Net force = 30 N

Acceleration = ?

Solution:

Acceleration can be determine through following formula,

F = m × a

a = F/m

Unit:

The unit of acceleration is m.s⁻².

Now we will put the values in formula.

a = 30 N/60 kg

a = 30 Kgm/s² / 60 kg

a = 0.5 m/s²
