Sully is riding a snowmobile on a flat, snow-covered surface with a constant velocity of 10 meters/second. the total mass of the snowmobile, including sully, is 280 kilograms. if sully accelerates to a velocity of 16 meters/second over 10 seconds, what’s the force exerted by the snowmobile to accelerate? use f = ma, where . 160 n 168 n 248 n 280 n 324 n

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
