Question

( x=4 t^{2}+5 t quad y=frac{7}{8} t )
( t_{x}=8 t+5 quad, quad v_{y}=7 / 8 )
( a_{x}=8 quad a_{4}=0 )
( therefore quad a=sqrt{a_{x}^{2}+a_{y}^{2}}=8 m / s^{2} )

# Tu Dllas su 67. A particle moves in x -y plane according to equations: x = 41° +5t and y = The acceleration of the particle must be (a) 8 m/s2 (b) 12 m/s2 (c) 16 m/s2 (d) none of these
