400N
300N
283N
212N
Correct answer is D
momentum force = Rsin\(\theta\) - \(\mu\)Rcos\(\theta\)
Fm = (40 x 10 x sin 45) - (40 x 10 x 0.25 x cos 45)
= 212N

Correct answer is C
P.E = mgh = 1000m joules
K.E = \(\frac{1}{2}\)mv2 = 200m joules
%converted = \(\frac{200m}{1000m}\) x 100
= 20%

160J
Correct answer is C
X = ut + \(\frac{1}{2}\)at2
= (0 x 4) + (\(\frac{1}{2}\) x 0.1 x 4 x 4)
= 0.8m
workdone = force x distance
= 40 x 0.8
= 32J
2.5ms-2
5.0ms-2
7.5ms-2
10.0ms-2
Correct answer is A
a = \(\frac{F}{m}\)
= \(\frac{60000 -(4800 \times10)}{4800}\)
= 2.5ms-2
