Need help with this physics problem?

Keith is pulling a sleigh full of cranky children across a patch of ice (assume no friction). The total mass

of the sleigh + children is 5Ō kg. If Keith applies a force of 2ŌO N at an angle of 37° to the horizontal,

find the acceleration of the sleigh.

    Motive force Fm = F*cos 37° = 200*0.8 = 160 N

    acceleration a = Fm/m = 160/50 = 16/5 = 3.2 m/sec^2

    Cos 37= .8.>>200*.8=160.>>1.6e^2/5.0e^1= 3.2m/s^2.
