Answer:

450000 kg m/s

Explanation:

convert 108km/h to m/s

1km=100m

1h=(60×60)s = 3600s

108km/h= (108×1000)÷3600

=30m/s

K.E =1/2mv^2

=1/2(1×10^3)(30^2)

= 1/2 × 1000 × 900

= 450000 kg m/s

this should be your answer, hope I was able to help.

A student produces a power of p = 0.87 kw while pushing a block of mass m = 75 kg on an inclined surface making an angle of Î¸ =

Paul [167]

When block is pushed upwards along the inclined plane

the net force applied on the block will be given as

$F_{net} = mg sin\theta + \mu_k mg cos\theta$

here we know that

m = 75 kg

$\theta = 8.5 degree$

$\mu_k = 0.16$

now plug in all values into this

$F_{net} = 75\times 9.8 sin8.5 + 0.16 \times 75\times 9.8 cos8.5$

$F = 225 N$

now for finding the power is given as

$P = Fv$

$0.87 \times 10^3 = 225 \time v$

$v = \frac{870}{225} = 3.87 m/s$
